CVE-2024-23897
Jenkins 2.441 and earlier, LTS 2.426.2 and earlier does not disable a feature of its CLI command parser that replaces an '@' character followed by a file path in an argument with the file's contents, allowing unauthenticated attackers to read arbitrary files on the Jenkins controller file system.

The summary, impact and action text on this page are written by our AI analysis pipeline, or taken from the NVD description when a CVE was imported from NVD. They are not the vendor's wording: check them against the sources. A longer AI executive summary and technical analysis are generated for signed-in accounts on the Max plan.
Affected products

|---|---|---|
| jenkinsfrom the Bitnami advisory, via OSV | < 2.452.1Vendor says fixed in: 2.452.1 |
As published in the CVE Program record, and, for products that ship the affected component, in the advisory named beside them. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.

Fix and mitigation
WAF and other mitigations
Can a WAF block it? Yes. Path traversal sends `../` sequences in the request, which WAF rules catch, including the common encodings.
Also consider: canonical path validation
Based on the weakness type only; no CVE-specific evidence yet. We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.

Common questions
Is CVE-2024-23897 being exploited?
Yes. CVE-2024-23897 appears in CISA's Known Exploited Vulnerabilities catalog, which means exploitation in the wild has been confirmed and reported. Treat it as active rather than theoretical, and patch it ahead of higher-scoring vulnerabilities that carry no exploitation evidence.
How severe is CVE-2024-23897?
CVE-2024-23897 is rated Critical with a CVSS score of 9.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2024-23897?
Yes. A fix has been recorded for CVE-2024-23897. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2024-23897 affect?
CVE-2024-23897 affects jenkins:jenkins. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
