Cisco IOS software 11.3 through 12.2 running on Cisco uBR7200 and uBR7100 series Universal Broadband Routers allows remote attackers to modify Data Over Cable Service Interface Specification (DOCSIS) settings via a DOCSIS file without a Message Integrity Check (MIC) signature, which is approved by the router.
CVE-2026-39395 1 Sigstore 1 Cosign 2026-04-15 4.3 Medium
Cosign provides code signing and transparency for containers and binaries. Prior to 3.0.6 and 2.6.3, cosign verify-blob-attestation may erroneously report a "Verified OK" result for attestations with malformed payloads or mismatched predicate types. For old-format bundles and detached signatures, this was due to a logic flaw in the error handling of the predicate type validation. For new-format bundles, the predicate type validation was bypassed completely. This vulnerability is fixed in 3.0.6 and 2.6.3.
CVE-2026-32614 1 Emmansun 1 Gmsm 2026-04-15 7.5 High
Go ShangMi (Commercial Cryptography) Library (GMSM) is a cryptographic library that covers the Chinese commercial cryptographic public algorithms SM2/SM3/SM4/SM9/ZUC. Prior to 0.41.1, the current SM9 decryption implementation contains an infinity-point ciphertext forgery vulnerability. The root cause is that, during decryption, the elliptic-curve point C1 in the ciphertext is only deserialized and checked to be on the curve, but the implementation does not explicitly reject the point at infinity. In the current implementation, an attacker can construct C1 as the point at infinity, causing the bilinear pairing result to degenerate into the identity element in the GT group. As a result, a critical part of the key derivation input becomes a predictable constant. An attacker who only knows the target user's UID can derive the decryption key material and then forge a ciphertext that passes the integrity check. This vulnerability is fixed in 0.41.1.
CVE-2025-40758 1 Mendix 2 Mendix, Saml 2026-04-15 8.7 High
A vulnerability has been identified in Mendix SAML (Mendix 10.12 compatible) (All versions < V4.0.3), Mendix SAML (Mendix 10.21 compatible) (All versions < V4.1.2), Mendix SAML (Mendix 9.24 compatible) (All versions < V3.6.21). Affected versions of the module insufficiently enforce signature validation and binding checks. This could allow unauthenticated remote attackers to hijack an account in specific SSO configurations.
CVE-2020-36843 2026-04-15 4.3 Medium
The implementation of EdDSA in EdDSA-Java (aka ed25519-java) through 0.3.0 exhibits signature malleability and does not satisfy the SUF-CMA (Strong Existential Unforgeability under Chosen Message Attacks) property. This allows attackers to create new valid signatures different from previous signatures for a known message.
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-2024-13990 1 Microworld Technologies 1 Escan 2026-04-15 N/A
MicroWorld eScan AV's update mechanism failed to ensure authenticity and integrity of updates: update packages were delivered and accepted without robust cryptographic verification. As a result, an on-path attacker could perform a man-in-the-middle (MitM) attack and substitute malicious update payloads for legitimate ones. The eScan AV client accepted these substituted packages and executed or loaded their components (including sideloaded DLLs and Java/installer payloads), enabling remote code execution on affected systems. MicroWorld eScan confirmed remediation of the update mechanism on 2023-07-31 but versioning details are unavailable. NOTE: MicroWorld eScan disputes the characterization in third-party reports, stating the issue relates to 2018–2019 and that controls were implemented then.
CVE-2024-1721 2026-04-15 N/A
Improper Verification of Cryptographic Signature vulnerability in HYPR Passwordless on Windows allows Malicious Software Update.This issue affects HYPR Passwordless: before 9.1.
CVE-2024-2451 2026-04-15 6.4 Medium
Improper fingerprint validation in the TeamViewer Client (Full & Host) prior Version 15.54 for Windows and macOS allows an attacker with administrative user rights to further elevate privileges via executable sideloading.
CVE-2024-32962 1 Node Saml Project 1 Xml Crypto 2026-04-15 10 Critical
xml-crypto is an xml digital signature and encryption library for Node.js. In affected versions the default configuration does not check authorization of the signer, it only checks the validity of the signature per section 3.2.2 of the w3 xmldsig-core-20080610 spec. As such, without additional validation steps, the default configuration allows a malicious actor to re-sign an XML document, place the certificate in a `<KeyInfo />` element, and pass `xml-crypto` default validation checks. As a result `xml-crypto` trusts by default any certificate provided via digitally signed XML document's `<KeyInfo />`. `xml-crypto` prefers to use any certificate provided via digitally signed XML document's `<KeyInfo />` even if library was configured to use specific certificate (`publicCert`) for signature verification purposes. An attacker can spoof signature verification by modifying XML document and replacing existing signature with signature generated with malicious private key (created by attacker) and by attaching that private key's certificate to `<KeyInfo />` element. This vulnerability is combination of changes introduced to `4.0.0` on pull request 301 / commit `c2b83f98` and has been addressed in version 6.0.0 with pull request 445 / commit `21201723d`. Users are advised to upgrade. Users unable to upgrade may either check the certificate extracted via `getCertFromKeyInfo` against trusted certificates before accepting the results of the validation or set `xml-crypto's getCertFromKeyInfo` to `() => undefined` forcing `xml-crypto` to use an explicitly configured `publicCert` or `privateKey` for signature verification.
CVE-2024-36277 2026-04-15 5.3 Medium
Improper verification of cryptographic signature issue exists in "FreeFrom - the nostr client" App versions prior to 1.3.5 for Android and iOS. The affected app cannot detect event data with invalid signatures.
