The vulnerability may allow attackers to extract files outside the intended extraction directory when malicious tar archives are processed. The strip_first_component filter splits the path on the first `/` and extracts the second component, while allowing `../` sequences. Paths like `dummy_dir/../../etc/passwd` become `../../etc/passwd`. Note that this suffers from a nested tarball attack as well with multi-level tar files such as `dummy_dir/inner.tar.gz`, where the inner.tar.gz includes a traversal `dummy_dir/../../config/.env` that also gets translated to `../../config/.env`. Version 6.1.0 contains a patch for the issue.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Enterprise Server 16.0:python313-jaraco.context-5.3.0-160000.3.1.noarch","SUSE Linux Enterprise Server for SAP applications 16.0:python313-jaraco.context-5.3.0-160000.3.1.noarch"]},"references":[{"category":"external","summary":"CVE-2026-23949","url":"https://www.suse.com/security/cve/CVE-2026-23949"},{"category":"external","summary":"SUSE Bug 1256954 for CVE-2026-23949","url":"https://bugzilla.suse.com/1256954"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Server 16.0:python313-jaraco.context-5.3.0-160000.3.1.noarch","SUSE Linux Enterprise Server for SAP applications 16.0:python313-jaraco.context-5.3.0-160000.3.1.noarch"]}],"scores":[{"cvss_v3":{"baseScore":7.4,"baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N","version":"3.1"},"products":["SUSE Linux Enterprise Server 16.0:python313-jaraco.context-5.3.0-160000.3.1.noarch","SUSE Linux Enterprise Server for SAP applications 16.0:python313-jaraco.context-5.3.0-160000.3.1.noarch"]}],"threats":[{"category":"impact","date":"2026-01-23T10:43:48Z","details":"important"}],"title":"CVE-2026-23949"}]}
