Detailsinfo

A vulnerability was found in CallBackery up to 0.61.x and classified as problematic. Affected by this issue is the function hmac_sha1_sum. The manipulation with an unknown input leads to a hash without salt vulnerability. Using CWE to declare the problem leads to CWE-759. The product uses a one-way cryptographic hash against an input that should not be reversible, such as a password, but the product does not also use a salt as part of the input. Impacted is confidentiality. CVE summarizes:

CallBackery versions before 0.62.0 for Perl store user passwords as unsalted HMAC-SHA1 hashes. Passwords are hashed with hmac_sha1_sum() from Mojo::Util with no key, a single fast SHA-1 HMAC. There is no salt, so equal passwords give equal hashes, and no work factor slows down guessing. An attacker who obtains the user table can recover passwords by fast offline guessing.

The advisory is available at metacpan.org. This vulnerability is handled as CVE-2026-13576 since 06/28/2026. The exploitation is known to be easy. The attack may be launched remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1110.002 by the MITRE ATT&CK project.

Upgrading to version 0.62.0 eliminates this vulnerability.
