| Package | Affected versions | Patched versions |
|---|---|---|
| dovecot | ≥ 2.3.11, < 2.3.14.1 | 2.3.14.1 |
Dovecot before 2.3.15 allows ../ Path Traversal. An attacker with access to the local filesystem can trick OAuth2 authentication into using an HS256 validation key from an attacker-controlled location. This occurs during use of local JWT validation with the posix fs driver.
