| CVE-2026-33487 | 1 Russellhaering | 1 Goxmldsig | 2026-03-27 | 7.5 High |
| goxmlsig provides XML Digital Signatures implemented in Go. Prior to version 1.6.0, the `validateSignature` function in `validate.go` goes through the references in the `SignedInfo` block to find one that matches the signed element's ID. In Go versions before 1.22, or when `go.mod` uses an older version, there is a loop variable capture issue. The code takes the address of the loop variable `_ref` instead of its value. As a result, if more than one reference matches the ID or if the loop logic is incorrect, the `ref` pointer will always end up pointing to the last element in the `SignedInfo.References` slice after the loop. goxmlsig version 1.6.0 contains a patch. | ||||
| CVE-2024-8698 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On and 1 more | 2026-03-27 | 7.7 High |
| A flaw exists in the SAML signature validation method within the Keycloak XMLSignatureUtil class. The method incorrectly determines whether a SAML signature is for the full document or only for specific assertions based on the position of the signature in the XML document, rather than the Reference element used to specify the signed element. This flaw allows attackers to create crafted responses that can bypass the validation, potentially leading to privilege escalation or impersonation attacks. | ||||
| CVE-2026-20699 | 1 Apple | 1 Macos | 2026-03-25 | 6.2 Medium |
| A downgrade issue affecting Intel-based Mac computers was addressed with additional code-signing restrictions. This issue is fixed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.3, macOS Tahoe 26.4. An app may be able to access user-sensitive data. | ||||
| CVE-2026-4600 | 2 Jsrsasign Project, Kjur | 2 Jsrsasign, Jsrsasign | 2026-03-25 | 7.4 High |
| Versions of the package jsrsasign before 11.1.1 are vulnerable to Improper Verification of Cryptographic Signature via the DSA domain-parameter validation in KJUR.crypto.DSA.setPublic (and the related DSA/X509 verification flow in src/dsa-2.0.js). An attacker can forge DSA signatures or X.509 certificates that X509.verifySignature() accepts by supplying malicious domain parameters such as g=1, y=1, and a fixed r=1, which make the verification equation true for any hash. | ||||

| CVE-2026-27962 | 1 Authlib | 1 Authlib | 2026-03-24 | 9.1 Critical |
| Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to version 1.6.9, a JWK Header Injection vulnerability in authlib's JWS implementation allows an unauthenticated attacker to forge arbitrary JWT tokens that pass signature verification. When key=None is passed to any JWS deserialization function, the library extracts and uses the cryptographic key embedded in the attacker-controlled JWT jwk header field. An attacker can sign a token with their own private key, embed the matching public key in the header, and have the server accept the forged token as cryptographically valid — bypassing authentication and authorization entirely. This issue has been patched in version 1.6.9. | ||||
| CVE-2026-4258 | 1 Bitwiseshiftleft | 1 Sjcl | 2026-03-24 | 7.5 High |
| All versions of the package sjcl are vulnerable to Improper Verification of Cryptographic Signature due to missing point-on-curve validation in sjcl.ecc.basicKey.publicKey(). An attacker can recover a victim's ECDH private key by sending crafted off-curve public keys and observing ECDH outputs. The dhJavaEc() function directly returns the raw x-coordinate of the scalar multiplication result (no hashing), providing a plaintext oracle without requiring any decryption feedback. | ||||
| CVE-2026-3564 | 1 Connectwise | 1 Screenconnect | 2026-03-24 | 9 Critical |
| A condition in ScreenConnect may allow an actor with access to server-level cryptographic material used for authentication to obtain unauthorized access, including elevated privileges, in certain scenarios. | ||||
| CVE-2026-32294 | 1 Jetkvm | 1 Jetkvm | 2026-03-24 | 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-2025-52648 | 2026-03-24 | 4.8 Medium | ||
| HCL AION is affected by a vulnerability where offering images are not digitally signed. Lack of image signing may allow the use of unverified or tampered images, potentially leading to security risks such as integrity compromise or unintended behavior in the system | ||||
| CVE-2026-20989 | 2 Samsung, Samsung Mobile | 2 Android, Samsung Mobile Devices | 2026-03-23 | 2.4 Low |
| Improper verification of cryptographic signature in Font Settings prior to SMR Mar-2026 Release 1 allows physical attackers to use custom font. | ||||
| CVE-2026-32614 | 1 Emmansun | 1 Gmsm | 2026-03-23 | 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-2026-3562 | 1 Phillips | 1 Hue Bridge | 2026-03-23 | N/A |
| Philips Hue Bridge hk_hap Ed25519 Signature Verification Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Philips Hue Bridge. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ed25519_sign_open function. The issue results from improper verification of a cryptographic signature. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-28480. | ||||
| CVE-2026-32597 | 2 Jpadilla, Pyjwt Project | 2 Pyjwt, Pyjwt | 2026-03-23 | 7.5 High |
| PyJWT is a JSON Web Token implementation in Python. Prior to 2.12.0, PyJWT does not validate the crit (Critical) Header Parameter defined in RFC 7515 §4.1.11. When a JWS token contains a crit array listing extensions that PyJWT does not understand, the library accepts the token instead of rejecting it. This violates the MUST requirement in the RFC. This vulnerability is fixed in 2.12.0. | ||||
| CVE-2026-4478 | 1 Yitechnology | 1 Yi Home Camera | 2026-03-20 | 8.1 High |
