What it is stated by the CNA
Traefik is an open source HTTP reverse proxy and load balancer. Versions prior to 2.9.6 are subject to a potential vulnerability in Traefik displaying the Authorization header in its debug logs. In certain cases, if the log level is set to DEBUG, credentials provided using the Authorization header are displayed in the debug logs. Attackers must have access to a users logging system in order for credentials to be stolen. This issue has been addressed in version 2.9.6. Users are advised to upgrade. Users unable to upgrade may set the log level to `INFO`, `WARN`, or `ERROR`.

What would change this brief held, dated
- CISA KEV
- Not listed in the catalogue we hold. A listing changes this brief.
- exploit probability
- 0.01 on 2026-10-08 (FIRST's EPSS, a probability and not evidence of exploitation). Next band line: 10% (0.10). Crossing a line changes this brief.
- fix

How to check this
Every value above is held with two dates: when it was true upstream (as_of) and when we recorded it (tx_from). Re-derive the exploit probability as it stood on any date:
SELECT value, source, source_version, as_of, tx_from
FROM volatile_valid_as_of('CVE-2022-23469', '2026-10-31T23:59:59.999999Z', now());
