CVE-2026-70667 Lemur: SSRF protection in certificate revocation checking bypassable via HTTP redirects and DNS rebinding (incomplete fix for CVE-2026-55162)

Lemur manages TLS certificate creation. Prior to 1.9.3, validaterevocationurl in lemur/certificates/verify.py checked the original CRL or OCSP URL but the later request could reach a different destination. The CRL requests.get call followed HTTP redirects without validating each Location target, ...

CVE-2026-55164 Lemur: Plaintext password storage in Lemur user-update path

Lemur manages TLS certificate creation. Prior to 1.9.2, lemur.users.service.update assigned a replacement password directly to users.password, while lemur/users/models.py registered User.hashpassword only for the beforeinsert event. Because no beforeupdate listener ran, administrator-initiated...

CVE-2026-55162 Lemur: Post-authentication SSRF via certificate verification - attacker-controlled CRL and OCSP URLs in uploaded certificates

Lemur manages TLS certificate creation. Prior to 1.9.2, lemur/certificates/verify.py accepted CRL Distribution Point and OCSP responder URLs from uploaded certificate extensions and used them in crlverify and ocspverify without adequate destination validation. An authenticated operator could subm...

CVE-2026-55166 Lemur: any SSO-authenticated user achieves AWS IAM compromise and permanent PKI key access via ACME acme_url SSRF and creator-equality IDOR

Lemur manages TLS certificate creation. Prior to 1.9.2, authenticated users could influence an ACME authority acmeurl without an effective server-side destination restriction and trigger AcmeHandler.setupacmeclient to make backend requests. An attacker could target cloud instance metadata or...

CVE-2026-55163 Lemur: Privilege escalation via PUT /api/1/roles/<id> — non-admin role members can rewrite role membership

Lemur manages TLS certificate creation. Prior to 1.9.2, PUT /api/1/roles/ in lemur/roles/views.py:298 authorized updates with RoleMemberPermissionroleid, which allowed either an administrator or any existing member of the target role.

CVE-2026-55165 Lemur : JWT verifier trusts attacker-supplied alg from token header — defense-in-depth gap; chain-dependent ATO with secret disclosure

Lemur manages TLS certificate creation. Prior to 1.9.2, the JWT verifier in lemur/auth/service.py:130-137 used fetchtokenheader to read headerdata"alg" from an unverified token and passed that attacker-controlled value to decodewithmultiplesecrets. PyJWT 2.x rejects alg=none with the configured...
