CVE-2025-58060: cups has Authentication bypass with AuthType Negotiate
Noroxi assessment
Priority: Monitor (action score 32/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.98% (FIRST EPSS); higher than 62.7% of all records.
- Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: azl3 cups 2.4.10-1 on Azure Linux 3.0 2.4.13-1; cbl2 cups 2.3.3op2-9 on CBL Mariner 2.0 2.3.3op2-10.
Low priority for now. Upgrade to azl3 cups 2.4.10-1 on Azure Linux 3.0 2.4.13-1; cbl2 cups 2.3.3op2-9 on CBL Mariner 2.0 2.3.3op2-10 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.12 and earlier, when the `AuthType` is set to anything but `Basic`, if the request contains an `Authorization: Basic ...` header, the password is not checked. This results in authentication bypass. Any configuration that allows an `AuthType` that is not `Basic` is affected. Version 2.4.13 fixes the issue.

Root cause
Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.
