Source Verification: Read both snapshots from disk (gunzip): source-0.html.gz (The Hacker News, Swati Khandelwal, dated Sep 29, 2026, HTTP 200) and source-1.html.gz (GitHub advisory GHSA-qx49-fqc8-xw99, HTTP 200). manifest suspicious_patterns is null for both; nothing to assess. Verified verbatim: GHSA ID GHSA-qx49-fqc8-xw99; advisory published Sep 28, 2026, severity High, CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), 6.5 for interactive provider (UI:R); 'No known CVE' on advisory and THN 'No CVE had been assigned as of September 29'; affected 1.9.1 through 1.29.1 and 2.0.0 through 2.1.1; patched 1.30.0 and 2.2.0; affected classes OAuthClientProvider, ClientCredentialsOAuthProvider, PrivateKeyJWTOAuthProvider, deprecated 1.x RFC7523OAuthClientProvider; not affected: SDK-built servers, stdio clients, clients attaching own tokens. Extra step: THN quotes advisory 'upgrading changes nothing until you also pass issuer=' for ClientCredentialsOAuthProvider and PrivateKeyJWTOAuthProvider (advisory: 'upgrading changes nothing until you also pass issuer='); DeprecationWarning on 1.30.0 hidden by default; RFC7523OAuthClientProvider has no issuer option. Quotes 'the MCP server a client connected to decide where the client's OAuth credentials were sent', 'rotate its client secret and revoke its tokens at the authorization server', 'no workaround other than connecting OAuth-enabled clients only to MCP servers you trust' all verbatim in advisory; 'the SDK did not always check that answer', 'so nothing looks wrong', 'which Python hides by default, so it is easy to miss', and the MCP definition all verbatim in THN. Timing claim: THN states outright 'The issuer checks shipped in the 1.30.0 and 2.2.0 release notes on September 7... The advisory followed on September 28, the same day Cycode published its writeup. The advisory credits eight reporters'; the advisory lists exactly eight reporters and shows Sep 28, 2026, matching the article's Sept 28 date. Cycode attribution and 'no attacks reported' are THN statements, correctly attributed. Minor non-issue: advisory notes PrivateKeyJWTOAuthProvider leaks a signed client assertion rather than a client secret; article follows THN's summary wording.
