CVE-2026-65905

Authentication Bypass by Capture-replay vulnerability in Apache Tomcat's DIGEST authenticator. If, before windowSize requests have been made, a client makes a DIGEST authenticated request with a nonceCount on the upper boundary of the replay window then that request is replayable once only while...

CVE-2026-58085

CVE-2026-58085 is a missing MAC validation flaw in the wg(4) kernel driver (if_wg) of FreeBSD , which implements the WireGuard VPN protocol. After dispatching a ChaCha20-Poly1305 decrypt operation to the OpenCrypto framework (OCF) , the driver failed to verify whether the Poly1305 MAC step succee...

FreeBSD -- Missing MAC validation in wg(4) packet decryption

Problem Description: After dispatching a decrypt operation to OCF and receiving the result, the wg4 driver failed to check whether the MAC verification step succeeded. The driver thus silently accepted packets with an invalid Poly1305 authentication tag. Impact: A remote attacker who can send UDP...

Pterodactyl TOTPs can be reused during validity window

Summary When a user signs into an account with 2FA enabled they are prompted to enter a token. When that token is used, it is not sufficiently marked as used in the system allowing an attacker that intercepts that token to then use it in addition to a known username/password during the token...

FreeBSD -- Missing IPsec anti-replay window check

Problem Description: A missing check means that an attacker can reinject an old packet and it will be accepted and processed by the IPsec endpoint. Impact: The impact depends on the higher-level protocols in use over IPsec. For example, an attacker who can capture and inject packets could cause a...
