GHSA-V5RC-CPWC-CFPR Lemur: Incomplete fix for GHSA-v2wp-frmc-5q3v -- ACME authority update endpoint allows non-admin to replace `acme_url` with internal IP, bypassing allowlist

Summary The fix for GHSA-v2wp-frmc-5q3v added validateacmeurl to reject acmeurl values not in ACMEDIRECTORYHOSTALLOWLIST, but the validation is only called at authority creation time POST. The authority update endpoint PUT /api/1/authorities/ accepts and stores arbitrary options -- including a...

Lemur: Server-Side Request Forgery via the ACME client following server-controlled URLs

Summary The ACME client used to issue certificates from Let's Encrypt / Google Public CA / private ACME CAs connects to an acmeurl, 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...

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...

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...
