| CVE-2026-33746 | 1 Convoypanel | 2 Convoy, Panel | 2026-04-16 | 9.8 Critical |
| Convoy is a KVM server management panel for hosting businesses. From version 3.9.0-beta to before version 4.5.1, the JWTService::decode() method did not verify the cryptographic signature of JWT tokens. While the method configured a symmetric HMAC-SHA256 signer via lcobucci/jwt, it only validated time-based claims (exp, nbf, iat) using the StrictValidAt constraint. The SignedWith constraint was not included in the validation step. This means an attacker could forge or tamper with JWT token payloads — such as modifying the user_uuid claim — and the token would be accepted as valid, as long as the time-based claims were satisfied. This directly impacts the SSO authentication flow (LoginController::authorizeToken), allowing an attacker to authenticate as any user by crafting a token with an arbitrary user_uuid. This issue has been patched in version 4.5.1. | ||||
| CVE-2026-29000 | 1 Pac4j | 1 Pac4j | 2026-04-16 | 9.1 Critical |
| pac4j-jwt versions prior to 4.5.9, 5.7.9, and 6.3.3 contain an authentication bypass vulnerability in JwtAuthenticator when processing encrypted JWTs that allows remote attackers to forge authentication tokens. Attackers who possess the server's RSA public key can create a JWE-wrapped PlainJWT with arbitrary subject and role claims, bypassing signature verification to authenticate as any user including administrators. | ||||
| CVE-2026-28802 | 1 Authlib | 1 Authlib | 2026-04-16 | 9.8 Critical |
| Authlib is a Python library which builds OAuth and OpenID Connect servers. From version 1.6.5 to before version 1.6.7, previous tests involving passing a malicious JWT containing alg: none and an empty signature was passing the signature verification step without any changes to the application code when a failure was expected.. This issue has been patched in version 1.6.7. | ||||
| CVE-2026-28432 | 1 Misskey | 1 Misskey | 2026-04-16 | 7.5 High |

| Grandstream BudgeTone (BT) 100 Voice over IP (VoIP) phones do not properly check the Call-ID, branch, and tag values in a NOTIFY message to verify a subscription, which allows remote attackers to spoof messages such as the "Messages waiting" message. | ||||
| CVE-2005-2181 | 1 Cisco | 4 Ip Phone 7940, Ip Phone 7940 Firmware, Ip Phone 7960 and 1 more | 2026-04-16 | 7.5 High |
| Cisco 7940/7960 Voice over IP (VoIP) phones do not properly check the Call-ID, branch, and tag values in a NOTIFY message to verify a subscription, which allows remote attackers to spoof messages such as the "Messages waiting" message. | ||||
| CVE-2002-1796 | 1 Hp | 5 Chaivm Ezloader, Laserjet 4100, Laserjet 4500 and 2 more | 2026-04-16 | 7.8 High |
| ChaiVM EZloader for HP color LaserJet 4500 and 4550 and HP LaserJet 4100 and 8150 does not properly verify JAR signatures for new services, which allows local users to load unauthorized Chai services. | ||||
| 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-2025-58356 | 1 Edgelesssys | 1 Constellation | 2026-04-15 | N/A |
| Constellation is the first Confidential Kubernetes. The Constellation CVM image uses LUKS2-encrypted volumes for persistent storage. When opening an encrypted storage device, the CVM uses the libcryptsetup function crypt_activate_by_passhrase. If the VM is successful in opening the partition with the disk encryption key, it treats the volume as confidential. However, due to the unsafe handling of null keyslot algorithms in the cryptsetup 2.8.1, it is possible that the opened volume is not encrypted at all. Cryptsetup prior to version 2.8.1 does not report an error when processing LUKS2-formatted disks that use the cipher_null-ecb algorithm in the keyslot encryption field. This vulnerability is fixed in 2.24.0. | ||||
| CVE-2024-11957 | 1 Kingsoft | 1 Wps Office | 2026-04-15 | N/A |
| Improper verification of the digital signature in ksojscore.dll in Kingsoft WPS Office in versions equal or less than 12.1.0.18276 on Windows allows an attacker to load an arbitrary Windows library. The patch released in version 12.2.0.16909 to mitigate CVE-2024-7262 was not restrictive enough. | ||||
| 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. | ||||
