CVE-2026-54491 Koel: Incomplete fix for CVE-2026-47260 — systemic SSRF in podcast & radio fetch paths

Koel is a free, open-source music streaming solution. Prior to 9.7.1, outbound podcast and radio fetch paths perform a point-in-time App\Helpers\Network::isPublicHost or isSafeUrl check without pinning the validated address, and most paths lack redirect-hop validation and do not revalidate every...

CVE-2026-54491

Koel versions prior to 9.7.1 contain an authenticated SSRF: any low-privilege user can supply a URL that 302-redirects to internal addresses or cloud metadata IPs (e.g., 169.254.169.254), since isPublicHost()/isSafeUrl() checks are point-in-time with no IP pinning and per-hop redirect validation ...

EUVD-2026-62701

Wekan is open source kanban built with Meteor. From 8.36 until 9.74, the outgoing webhook Integration URL validator in models/integrations.js checked only the literal URL.hostname against regular expressions, so DNS names such as 169-254-169-254.nip.io passed that first-line check. The delivery...

CVE-2026-75583

keeper.sh's calendar module version prior to 2.18.14 contains a server-side request forgery SSRF guard bypass vulnerability that allows authenticated attackers to reach private network addresses by exploiting a DNS rebinding attack against the two-phase URL validation and connection flow. The SSR...

CVE-2026-75583

keeper.sh calendar module versions prior to 2.18.14 contain an SSRF guard bypass vulnerability exploitable via DNS rebinding . The root cause is a design flaw in the two-phase URL validation flow: the SSRF guard resolves and validates a hostname's IP addresses but discards them before the actual ...

PYSEC-2026-3687 MLflow: Unauthenticated full-read SSRF in webhook delivery: _validate_webhook_url bypassed via unvalidated HTTP redirects (and DNS rebinding)

Summary The default MLflow Tracking Server mlflow server, no authentication, default SQLite backend exposes the model-registry webhooks API unauthenticated, including a synchronous POST /api/2.0/mlflow/webhooks/id/test endpoint that returns the upstream response status and body to the caller. The...

GHSA-F3QQ-49M6-RW8F Lemur: SSRF protection in certificate revocation checking bypassable via HTTP redirects and DNS rebinding (incomplete fix for GHSA-54vg-pfh7-jq95)

Summary The SSRF mitigation added for GHSA-54vg-pfh7-jq95 validaterevocationurl in lemur /certificates/verify.py can be bypassed. An operator-role user who uploads a certificate with attacker-controlled CRL/OCSP extensions can still make Lemur reach internal destinations RFC1918, loopback,...

CVE-2026-70667

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.

CVE-2026-70667

Netflix Lemur prior to 1.9.3 contains a bypass of its SSRF mitigation in _validate_revocation_url (lemur/certificates/verify.py).
