# Security digest: January 24, 2024

1 editorial brief, 1 known exploited (cisa kev) addition and 1 critical advisory.

## Take stock

- Act now: Jenkins CLI Arbitrary File Read (CVE-2024-23897) . Operators of Jenkins weekly 2.441 or earlier or LTS 2.426.2 or earlier, especially controllers reachable from the internet or with anonymous read or open signup.
- Do you run any of these? Atlassian Confluence Data Center and Server. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2024-02-14.
- Maven: 1 critical advisory ( org.jenkins-ci.main:jenkins-core ). Check with mvn dependency:tree -Dincludes=<groupId>:<artifactId> .
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Editorial briefs

- **Act now** [Jenkins CLI Arbitrary File Read (CVE-2024-23897)](https://erroneo.us/security/briefs/jenkins-cli-args4j-arbitrary-file-read/index.md): An unpatched Jenkins controller reachable by untrusted users leaks files and secrets that can lead to full takeover; upgrade now or disable the CLI.
