# Patch Next advisory brief: CVE-2026-10775 Advisory: SGLang is Vulnerable to DoS via the data_hash Function IDs: CVE-2026-10775, GHSA-jrcc-j37m-v8fg Record: https://patchnext.com/advisories/cve-2026-10775 (revision 3, source checked 26 Oct 2026, 13:50 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: Low (CVSS 1.1) Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed. ## Affected components - PyPI sglang: affected <= 0.5.11 ## Suggested inspection (read-only) - `python -m pip show sglang`: prints the installed version. Run with the environment that serves production active. ## Supported action No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything. ## Required regression checks - Run the test suite and a production build. - Exercise the features that depend on sglang. - Repeat the inspection and confirm that only fixed versions remain installed. ## Rollback considerations - Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward. ## Unresolved questions - Which deployments run an affected version? - Exploitation status can change. Check again before lowering the priority. - Mark the work resolved only after the fixed version is verified in production. ## Sources - Verified: https://osv.dev/vulnerability/GHSA-jrcc-j37m-v8fg (OSV record GHSA-jrcc-j37m-v8fg lists affected ranges: PyPI sglang >=0 <=0.5.11) - Verified: https://github.com/advisories/GHSA-jrcc-j37m-v8fg (GitHub-reviewed advisory GHSA-jrcc-j37m-v8fg lists affected ranges: PyPI sglang >=0 <=0.5.11) Commands are suggestions: review each one before running it.
