CVE-2026-3562 1 Philips 2 Hue Bridge V2, Hue Bridge V2 Firmware 2026-06-17 N/A 8.8 HIGH
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-2026-38651 1 Netmaker 1 Netmaker 2026-06-17 N/A 8.2 HIGH
Authentication Bypass vulnerability exists in Netmaker versions prior to 1.5.0. The VerifyHostToken function in logic/jwts.go fails to validate the JWT signature when verifying host tokens. An attacker can forge a JWT signed with any arbitrary key and use it to impersonate any host in the network, gaining access to sensitive information
CVE-2026-34872 1 Arm 2 Mbed Tls, Tf-psa-crypto 2026-06-17 N/A 9.1 CRITICAL
An issue was discovered in Mbed TLS 3.5.x and 3.6.x through 3.6.5 and TF-PSA-Crypto 1.0. There is a lack of contributory behavior in FFDH due to improper input validation. Using finite-field Diffie-Hellman, the other party can force the shared secret into a small set of values (lack of contributory behavior). This is a problem for protocols that depend on contributory behavior (which is not the case for TLS). The attack can be carried by the peer, or depending on the protocol by an active network attacker (person in the middle).
CVE-2026-34068 1 Nimiq 1 Nimiq Proof-of-stake 2026-06-17 N/A 6.8 MEDIUM
nimiq-transaction provides the transaction primitive to be used in Nimiq's Rust implementation. Prior to version 1.3.0, the staking contract accepts `UpdateValidator` transactions that set `new_voting_key=Some(...)` while omitting `new_proof_of_knowledge`. this skips the proof-of-knowledge requirement that is needed to prevent BLS rogue-key attacks when public keys are aggregated. Because tendermint macro block justification verification aggregates validator voting keys and verifies a single aggregated BLS signature against that aggregate public key, a rogue-key voting key in the validator set can allow an attacker to forge a quorum-looking justification while only producing a single signature. While the impact is critical, the exploitability is low: The voting keys are fixed for the epoch, so the attacker would need to know the next epoch validator set (chosen through VRF), which is unlikely. The patch for this vulnerability is included as part of v1.3.0. No known workarounds are available.
CVE-2026-33117 1 Microsoft 1 Azure Sdk For Java 2026-06-17 N/A 9.1 CRITICAL
The Java Key Vault Keys library in the Azure SDK for Java contains an issue in the local cryptographic verification path where authentication tag comparison was implemented incorrectly. In affected applications that use the vulnerable local cryptography path, specially crafted encrypted input may bypass integrity verification checks. Operations delegated to the Key Vault service are not affected. The issue is addressed in version 4.10.6.
CVE-2026-33026 1 Nginxui 1 Nginx Ui 2026-06-17 N/A 9.1 CRITICAL
Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, the nginx-ui backup restore mechanism allows attackers to tamper with encrypted backup archives and inject malicious configuration during restoration. This issue has been patched in version 2.3.4.
CVE-2026-32974 1 Openclaw 1 Openclaw 2026-06-17 N/A 8.6 HIGH
OpenClaw before 2026.3.12 contains an authentication bypass vulnerability in Feishu webhook mode when only verificationToken is configured without encryptKey, allowing acceptance of forged events. Unauthenticated network attackers can inject forged Feishu events and trigger downstream tool execution by reaching the webhook endpoint.
CVE-2026-32883 1 Botan Project 1 Botan 2026-06-17 N/A 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-2026-32614 2026-06-17 N/A 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-2026-32294 1 Jetkvm 1 Kvm 2026-06-17 N/A 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-2026-31946 1 Frentix 1 Openolat 2026-06-17 N/A 9.8 CRITICAL
OpenOlat is an open source web-based e-learning platform for teaching, learning, assessment and communication. From version 10.5.4 to before version 20.2.5, OpenOLAT's OpenID Connect implicit flow implementation does not verify JWT signatures. The JSONWebToken.parse() method silently discards the signature segment of the compact JWT (header.payload.signature), and the getAccessToken() methods in both OpenIdConnectApi and OpenIdConnectFullConfigurableApi only validate claim-level fields (issuer, audience, state, nonce) without any cryptographic signature verification against the Identity Provider's JWKS endpoint. This issue has been patched in version 20.2.5.
CVE-2026-2968 1 Cesanta 1 Mongoose 2026-06-17 2.6 LOW 3.7 LOW
A vulnerability was detected in Cesanta Mongoose up to 7.20. This impacts the function mg_chacha20_poly1305_decrypt of the file /src/tls_chacha20.c of the component Poly1305 Authentication Tag Handler. The manipulation results in improper verification of cryptographic signature. The attack may be launched remotely. This attack is characterized by high complexity. The exploitability is said to be difficult. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-2746 1 Seppmail 1 Seppmail 2026-06-17 N/A 5.3 MEDIUM
SEPPmail Secure Email Gateway before version 15.0.1 does not properly communicate PGP signature verification results, leaving users unable to detect forged emails.
CVE-2026-28432 1 Misskey 1 Misskey 2026-06-17 N/A 7.5 HIGH
Misskey is an open source, federated social media platform. All Misskey servers prior to 2026.3.1 contain a vulnerability that allows bypassing HTTP signature verification. Although this is a vulnerability related to federation, it affects all servers regardless of whether federation is enabled or disabled. This vulnerability is fixed in 2026.3.1.
CVE-2026-27445 1 Seppmail 1 Seppmail 2026-06-17 N/A 5.3 MEDIUM
SEPPmail Secure Email Gateway before version 15.0.1 does not properly verify that a PGP signature was generated by the expected key, allowing signature spoofing.
CVE-2026-25922 1 Goauthentik 1 Authentik 2026-06-17 N/A 8.8 HIGH
authentik is an open-source identity provider. Prior to 2025.8.6, 2025.10.4, and 2025.12.4, when using a SAML Source that has the option Verify Assertion Signature under Verification Certificate enabled and not Verify Response Signature, or does not have the Encryption Certificate setting under Advanced Protocol settings configured, it was possible for an attacker to inject a malicious assertion before the signed assertion that authentik would use instead. authentik 2025.8.6, 2025.10.4, and 2025.12.4 fix this issue.
CVE-2026-25793 1 Slack 1 Nebula 2026-06-17 N/A 8.1 HIGH
Nebula is a scalable overlay networking tool. In versions from 1.7.0 to 1.10.2, when using P256 certificates (which is not the default configuration), it is possible to evade a blocklist entry created against the fingerprint of a certificate by using ECDSA Signature Malleability to use a copy of the certificate with a different fingerprint. This issue has been patched in version 1.10.3.
CVE-2026-24850 2026-06-17 N/A 5.3 MEDIUM
The ML-DSA crate is a Rust implementation of the Module-Lattice-Based Digital Signature Standard (ML-DSA). Starting in version 0.0.4 and prior to version 0.1.0-rc.4, the ML-DSA signature verification implementation in the RustCrypto `ml-dsa` crate incorrectly accepts signatures with repeated (duplicate) hint indices. According to the ML-DSA specification (FIPS 204 / RFC 9881), hint indices within each polynomial must be **strictly increasing**. The current implementation uses a non-strict monotonic check (`<=` instead of `<`), allowing duplicate indices. This is a regression bug. The original implementation was correct, but a commit in version 0.0.4 inadvertently changed the strict `<` comparison to `<=`, introducing the vulnerability. Version 0.1.0-rc.4 fixes the issue.
CVE-2026-24807 2026-06-17 N/A N/A
Improper Verification of Cryptographic Signature vulnerability in liuyueyi quick-media (plugins/svg-plugin/batik-codec-fix/src/main/java/org/apache/batik/ext/awt/image/codec/util modules). This vulnerability is associated with program files SeekableOutputStream.Java. This issue affects quick-media: before v1.0.
CVE-2026-24032 2026-06-17 N/A 7.3 HIGH
A vulnerability has been identified in SINEC NMS (All versions < V4.0 SP3 with UMC). The affected application contains an authentication weakness due to insufficient validation of user identity in the UMC component. This could allow an unauthenticated remote attacker to bypass authentication and gain unauthorized access to the application. (ZDI-CAN-27564)
