Actively exploited in the wild
CISA added this to its Known Exploited Vulnerabilities catalog on Jan 10, 2024. That signals real attacks, not theory.
Remediation deadline for government agencies: Jan 22, 2024.
Known to be used in ransomware campaigns.

Weakness class (CWE)
CWE-287 · Improper AuthenticationCVSS vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N
nvd-primary
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.
The bug in code
The whole CWE-287 classA representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.
