If an attacker gains access to cache storage (e.g., filesystem, Memcached, Redis, etc.), they can construct a crafted payload, poison the cache, and execute Python code. NOTE: a third party indicates that exploitation is extremely unlikely unless the machine is already compromised; in other cases, the attacker would be unable to write their payload to the cache and generate the required collision","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2021-33026","url":"https://www.suse.com/security/cve/CVE-2021-33026"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1186052 for CVE-2021-33026","url":"https://bugzilla.suse.com/1186052"}],"title":"SUSE CVE CVE-2021-33026","tracking":{"current_release_date":"2025-07-08T00:15:18Z","generator":{"date":"2023-02-15T03:40:41Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2021-33026","initial_release_date":"2023-02-15T03:40:41Z","revision_history":[{"date":"2023-02-15T03:40:41Z","number":"2","summary":"Current version"},{"date":"2025-01-01T04:25:17Z","number":"3","summary":"Current version"},{"date":"2025-02-15T04:59:51Z","number":"4","summary":"Current version"},{"date":"2025-02-17T05:22:30Z","number":"5","summary":"Current version"},{"date":"2025-07-08T00:15:18Z","number":"6","summary":"Current version"}],"status":"interim","version":"6"}}}
