RUSTSEC-2026-0211 Non-constant time Authentication Tag Check in AES-GCM Decryption

AES-GCM decryption used an implementation for checking the provided authentication tag against the recomputed authentication tag that was intended to be constant-time, but resulted in non-constant-time code generation in certain circumstances. Note that libcrux-aesgcm does not give guarantees on...

CVE-2026-15041

The CVE describes a flaw in 389 Directory Server (389-ds-base): non-constant-time comparison in the PBKDF2-SHA256 password verification uses standard memcmp() instead of a constant-time function. This could allow a remote attacker to leverage timing measurements of LDAP bind attempts to infer par...

PYSEC-2026-1416 Gradio apps vulnerable to timing attacks to guess password

Impact This security policy is with regards to a timing attack that allows users of Gradio apps to potentially guess the password of password-protected Gradio apps. This relies on the fact that string comparisons in Python terminate early, as soon as there is a string mismatch. Because Gradio app...

Information Exposure

Overview Affected versions of this package are vulnerable to Information Exposure via the Authorizer function. An attacker can determine valid usernames by measuring the response time difference between valid and invalid usernames during authentication attempts. Remediation There is no fixed...
