A stream WINDOW_UPDATE, or the zero-delta window update that every empty SETTINGS frame delivers to all streams, ends the wait without delivering any body data, and the loop starts a new full countdown. A client that sends one of these 9-byte frames before each countdown expires keeps read_body blocked, together with the stream process and whatever the application holds while reading, for as long as it likes.\n\nThis issue affects bandit: from 1.4.0 before 1.14.0.","categories":["Unclassified"],"product":"bandit","vendor":"mtrudel","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115269","source_modified_at":"2026-10-26T15:35:52.079Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"bandit","vendor":"mtrudel","versions":[{"lessThan":"1.14.0","status":"affected","version":"1.4.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115269","source_modified_at":"2026-10-26T15:35:52.079Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"bandit","vendor":"mtrudel","versions":[{"lessThan":"220b9dfd27f9a21305be2afc75cbe585ddc24e7a","status":"affected","version":"fff06efe3be962b484bd4d3eb339372fda5a231f","versionType":"git"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115269","source_modified_at":"2026-10-26T15:35:52.079Z","fetched_at":"2026-10-26T19:10:57.178988Z","package":{"name":"bandit","ecosystem":null},"version":"1.14.0","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115269","source_modified_at":"2026-10-26T15:35:52.079Z","fetched_at":"2026-10-26T19:10:57.178988Z","package":{"name":"bandit","ecosystem":null},"version":"220b9dfd27f9a21305be2afc75cbe585ddc24e7a","basis":"first unaffected version stated in the CVE record"}],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-26T13:30:24.621Z","modified_at":"2026-10-26T15:35:52.079Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-115269","fetched_at":"2026-10-26T19:10:57.178988Z","source_modified_at":"2026-10-26T15:35:52.079Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/mtrudel/bandit/security/advisories/GHSA-p2qv-vx88-385x","tags":["vendor-advisory","related"]},{"source":"CVE List","url":"https://cna.erlef.org/cves/CVE-2026-115269.html","tags":["related"]},{"source":"CVE List","url":"https://osv.dev/vulnerability/EEF-CVE-2026-115269","tags":["related"]},{"source":"CVE List","url":"https://github.com/mtrudel/bandit/commit/fff06efe3be962b484bd4d3eb339372fda5a231f","tags":["related"]},{"source":"CVE List","url":"https://github.com/mtrudel/bandit/commit/220b9dfd27f9a21305be2afc75cbe585ddc24e7a","tags":["patch"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-26T15:02:19.174445Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-26T15:35:52.079Z","content_hash":"c2e7416f1a5b71ff91d783b8f2b80c32fc8135ae69fbc63fab91db0b76078092"}}
