CVE-2024-8531 1 Schneider-electric 1 Data Center Expert 2026-04-15 7.2 High
CWE-347: Improper Verification of Cryptographic Signature vulnerability exists that could compromise the Data Center Expert software when an upgrade bundle is manipulated to include arbitrary bash scripts that are executed as root.
CVE-2025-31489 1 Minio 1 Minio 2026-04-15 7.5 High
MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. The signature component of the authorization may be invalid, which would mean that as a client you can use any arbitrary secret to upload objects given the user already has prior WRITE permissions on the bucket. Prior knowledge of access-key, and bucket name this user might have access to - and an access-key with a WRITE permissions is necessary. However with relevant information in place, uploading random objects to buckets is trivial and easy via curl. This issue is fixed in RELEASE.2025-04-03T14-56-28Z.
CVE-2025-31335 2026-04-15 4 Medium
The OpenSAML C++ library before 3.3.1 allows forging of signed SAML messages via parameter manipulation (when using SAML bindings that rely on non-XML signatures).
CVE-2025-24800 2026-04-15 N/A
Hyperbridge is a hyper-scalable coprocessor for verifiable, cross-chain interoperability. A critical vulnerability was discovered in the ismp-grandpa crate, that allowed a malicious prover easily convince the verifier of the finality of arbitrary headers.

CVE-2024-53267 1 Sigstore 1 Sigstore-java 2026-04-15 5.5 Medium
sigstore-java is a sigstore java client for interacting with sigstore infrastructure. sigstore-java has insufficient verification for a situation where a validly-signed but "mismatched" bundle is presented as proof of inclusion into a transparency log. This bug impacts clients using any variation of KeylessVerifier.verify(). The verifier may accept a bundle with an unrelated log entry, cryptographically verifying everything but fails to ensure the log entry applies to the artifact in question, thereby "verifying" a bundle without any proof the signing event was logged. This allows the creation of a bundle without fulcio certificate and private key combined with an unrelated but time-correct log entry to fake logging of a signing event. A malicious actor using a compromised identity may want to do this to prevent discovery via rekor's log monitors. The signer's identity will still be available to the verifier. The signature on the bundle must still be on the correct artifact for the verifier to pass. sigstore-gradle-plugin and sigstore-maven-plugin are not affected by this as they only provide signing functionality. This issue has been patched in v1.1.0 release with PR #856. All users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2024-54150 2026-04-15 9.1 Critical
cjwt is a C JSON Web Token (JWT) Implementation. Algorithm confusion occurs when a system improperly verifies the type of signature used, allowing attackers to exploit the lack of distinction between signing methods. If the system doesn't differentiate between an HMAC signed token and an RS/EC/PS signed token during verification, it becomes vulnerable to this kind of attack. For instance, an attacker could craft a token with the alg field set to "HS256" while the server expects an asymmetric algorithm like "RS256". The server might mistakenly use the wrong verification method, such as using a public key as the HMAC secret, leading to unauthorised access. For RSA, the key can be computed from a few signatures. For Elliptic Curve (EC), two potential keys can be recovered from one signature. This can be used to bypass the signature mechanism if an application relies on asymmetrically signed tokens. This issue has been addressed in version 2.3.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2025-47934 1 Openpgpjs 1 Openpgpjs 2026-04-15 N/A
OpenPGP.js is a JavaScript implementation of the OpenPGP protocol. Startinf in version 5.0.1 and prior to versions 5.11.3 and 6.1.1, a maliciously modified message can be passed to either `openpgp.verify` or `openpgp.decrypt`, causing these functions to return a valid signature verification result while returning data that was not actually signed. This flaw allows signature verifications of inline (non-detached) signed messages (using `openpgp.verify`) and signed-and-encrypted messages (using `openpgp.decrypt` with `verificationKeys`) to be spoofed, since both functions return extracted data that may not match the data that was originally signed. Detached signature verifications are not affected, as no signed data is returned in that case. In order to spoof a message, the attacker needs a single valid message signature (inline or detached) as well as the plaintext data that was legitimately signed, and can then construct an inline-signed message or signed-and-encrypted message with any data of the attacker's choice, which will appear as legitimately signed by affected versions of OpenPGP.js. In other words, any inline-signed message can be modified to return any other data (while still indicating that the signature was valid), and the same is true for signed+encrypted messages if the attacker can obtain a valid signature and encrypt a new message (of the attacker's choice) together with that signature. The issue has been patched in versions 5.11.3 and 6.1.1. Some workarounds are available. When verifying inline-signed messages, extract the message and signature(s) from the message returned by `openpgp.readMessage`, and verify the(/each) signature as a detached signature by passing the signature and a new message containing only the data (created using `openpgp.createMessage`) to `openpgp.verify`. When decrypting and verifying signed+encrypted messages, decrypt and verify the message in two steps, by first calling `openpgp.decrypt` without `verificationKeys`, and then passing the returned signature(s) and a new message containing the decrypted data (created using `openpgp.createMessage`) to `openpgp.verify`.
CVE-2018-25099 1 Dcit 1 Perl-cryptx 2026-04-15 9.8 Critical
In the CryptX module before 0.062 for Perl, gcm_decrypt_verify() and chacha20poly1305_decrypt_verify() do not verify the tag.
CVE-2026-33895 1 Digitalbazaar 1 Forge 2026-04-14 7.5 High
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, Ed25519 signature verification accepts forged non-canonical signatures where the scalar S is not reduced modulo the group order (`S >= L`). A valid signature and its `S + L` variant both verify in forge, while Node.js `crypto.verify` (OpenSSL-backed) rejects the `S + L` variant, as defined by the specification. This class of signature malleability has been exploited in practice to bypass authentication and authorization logic (see CVE-2026-25793, CVE-2022-35961). Applications relying on signature uniqueness (i.e., dedup by signature bytes, replay tracking, signed-object canonicalization checks) may be bypassed. Version 1.4.0 patches the issue.
CVE-2026-32883 2 Botan Project, Randombit 2 Botan, Botan 2026-04-14 5.9 Medium
Botan is a C++ cryptography library. From version 3.0.0 to before version 3.11.0, during X509 path validation, OCSP responses were checked for an appropriate status code, but critically omitted verifying the signature of the OCSP response itself. This issue has been patched in version 3.11.0.
CVE-2026-34840 2 Hackerbay, Oneuptime 2 Oneuptime, Oneuptime 2026-04-14 8.1 High
OneUptime is an open-source monitoring and observability platform. Prior to version 10.0.42, OneUptime's SAML SSO implementation (App/FeatureSet/Identity/Utils/SSO.ts) has decoupled signature verification and identity extraction. isSignatureValid() verifies the first <Signature> element in the XML DOM using xml-crypto, while getEmail() always reads from assertion[0] via xml2js. An attacker can prepend an unsigned assertion containing an arbitrary identity before a legitimately signed assertion, resulting in authentication bypass. This issue has been patched in version 10.0.42.
CVE-2026-0234 2 Palo Alto Networks, Paloaltonetworks 4 Cortex Xsiam Microsoft Teams Marketplace, Cortex Xsoar Microsoft Teams Marketplace, Cortex Xsiam and 1 more 2026-04-14 9.1 Critical
An improper verification of cryptographic signature vulnerability exists in Cortex XSOAR and Cortex XSIAM platforms during integration of Microsoft Teams that enables an unauthenticated user to access and modify protected resources.
CVE-2026-32294 1 Jetkvm 2 Jetkvm, Kvm 2026-04-10 4.7 Medium
JetKVM prior to 0.5.4 does not verify the authenticity of downloaded firmware files. An attacker-in-the-middle or a compromised update server could modify the firmware and the corresponding SHA256 hash to pass verification.
CVE-2026-21002 1 Samsung 1 Galaxy Store 2026-04-09 5.5 Medium
Improper verification of cryptographic signature in Galaxy Store prior to version 4.6.03.8 allows local attacker to install arbitrary application.
CVE-2017-13083 1 Akeo 1 Rufus 2026-04-07 N/A
Akeo Consulting Rufus prior to version 2.17.1187 does not adequately validate the integrity of updates downloaded over HTTP, allowing an attacker to easily convince a user to execute arbitrary code
CVE-2026-34377 2 Zcashfoundation, Zfnd 4 Zebra, Zebra-consensus, Zebra and 1 more 2026-04-07 8.1 High
ZEBRA is a Zcash node written entirely in Rust. Prior to zebrad version 4.3.0 and zebra-consensus version 5.0.1, a logic error in Zebra's transaction verification cache could allow a malicious miner to induce a consensus split. By matching a valid transaction's txid while providing invalid authorization data, a miner could cause vulnerable Zebra nodes to accept an invalid block, leading to a consensus split from the rest of the Zcash network. This would not allow invalid transactions to be accepted but could result in a consensus split between vulnerable Zebra nodes and invulnerable Zebra and Zcashd nodes. This issue has been patched in zebrad version 4.3.0 and zebra-consensus version 5.0.1.
CVE-2026-34240 1 Appsup-dart 1 Jose 2026-04-07 7.5 High
JOSE is a Javascript Object Signing and Encryption (JOSE) library. Prior to version 0.3.5+1, a vulnerability in jose could allow an unauthenticated, remote attacker to forge valid JWS/JWT tokens by using a key embedded in the JOSE header (jwk). The vulnerability exists because key selection could treat header-provided jwk as a verification candidate even when that key was not present in the trusted key store. Since JOSE headers are untrusted input, an attacker could exploit this by creating a token payload, embedding an attacker-controlled public key in the header, and signing with the matching private key. Applications using affected versions for token verification are impacted. This issue has been patched in version 0.3.5+1. A workaround for this issue involves rejecting tokens where header jwk is present unless that jwk matches a key already present in the application's trusted key store.
