Incorrect Implementation of Authentication Algorithm

Overview signxml is a Python XML Signature and XAdES library Affected versions of this package are vulnerable to Incorrect Implementation of Authentication Algorithm due to the improper handling of signature verification settings when requirex509 is set to false and hmackey is specified. An...

CVE-2025-48995

CVE-2025-48995 affects SignXML (Python implementation of W3C XML Signature) prior to 4.0.4. When verify() is called with require_x509=False and an HMAC secret (hmac_key=...), the timing-based vulnerability may leak information about the correct HMAC during the comparison, enabling reconstruction ...

Important: perl-Mojolicious

Issue Overview: Mojolicious versions from 0.999922 through 9.39 for Perl uses a hard coded string, or the application's class name, as a HMAC session secret by default. These predictable default secrets can be exploited to forge session cookies. An attacker who knows or guesses the secret could...
