CVE-2026-71303 Lemur: Incomplete fix for CVE-2026-55166 -- ACME authority update endpoint allows non-admin to replace `acme_url` with internal IP, bypassing allowlist
Lemur manages TLS certificate creation. Prior to 1.9.3, validateacmeurl enforced ACMEDIRECTORYHOSTALLOWLIST when an authority was created, but PUT /api/1/authorities/ passed options to lemur/authorities/service.py without applying the same check. A user holding an authority role could replace the...
CVE-2026-71303
In Lemur prior to 1.9.3, the PUT /api/1/authorities/ endpoint skipped the ACME_DIRECTORY_HOST_ALLOWLIST check applied at creation, letting any authority-role user set an internal or instance-metadata URL as the stored acme_url; the next issuance then made an outbound request via ClientV2.get_dire...
CVE-2026-55166
A low-privilege SSO-authenticated user chains three flaws in Netflix Lemur prior to 1.9.2: an unfiltered acme_url SSRF to AWS IMDS (CWE-918) exfiltrates worker STS credentials, while a creator-equality IDOR (CWE-639) at certificates/views.py:734 grants permanent private-key access after ownership...

Summary The fix for GHSA-v2wp-frmc-5q3v added validate acme url to reject acme url values not in ACME DIRECTORY HOST ALLOWLIST, but the validation is only called at authority creation time POST. The authority update endpoint PUT /api/1/authorities/ accepts and stores arbitrary options -- includin...
PT-2026-80334
Summary The ACME client used to issue certificates from Let's Encrypt / Google Public CA / private ACME CAs connects to an acme url, then issues requests to URLs that the ACME server returns in its directory/order/authorization/finalize responses - this is the classic ACME-client SSRF RFC 8555...
