CVE-2026-61699

nebula-mesh (forgekeep) is a self-hosted control plane for the Slack Nebula mesh VPN. Prior to v0.7.1 , the agent-side poller decodes the per-CA revocation blocklist from the server but discards it — it never writes pki.blocklist into the local config.yml, and the config generator has no field to...

CVE-2026-61699 nebula-mesh: Certificate revocation is never enforced at the mesh

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. Prior to version 0.7.1, revocation is the only in-band mechanism that isolates a compromised/offboarded host from a Nebula mesh. Because the blocklist never reaches any peer's config.yml, a Blocked host retains full overlay...

CVE-2026-53602

CVE-2026-53602 affects nebula-mesh , a self-hosted control plane for Slack Nebula mesh VPN (github.com/forgekeep/nebula-mesh), prior to version 0.3.7 . The core issue is that host revocation is not durable : blocked or offboarded hosts can regain a fresh, valid Nebula certificate because nebula-m...

CVE-2026-85525

A flaw was found in Snowflake drivers, including Python, Go, JDBC, and Node.js. This flaw involves improper Online Certificate Status Protocol OCSP response validation, which allows a revoked Transport Layer Security TLS certificate to be accepted as valid. A man-in-the-middle attacker, possessin...

Linux Distros Unpatched Vulnerability : CVE-2026-84964

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A double free in the OpenSSL-based TLS certificate revocation checking path of the MongoDB C Driver can be reached by a TLS endpoint that the client already...

Double Free

Overview Affected versions of this package are vulnerable to Double Free in the OCSP certificate revocation checking process during a TLS handshake with a trusted endpoint. An attacker can cause the client application to terminate unexpectedly by sending specially crafted certificate data that...

DEBIAN-CVE-2026-84964

A double free in the OpenSSL-based TLS certificate revocation checking path of the MongoDB C Driver can be reached by a TLS endpoint that the client already trusts. During the handshake, specially formed certificate data can cause the same heap object to be released twice. An unauthenticated part...

curl: Apple SecTrust fallback ignores CURLOPT_CRLFILE, letting a revoked cert pass

When libcurl is built with USEAPPLESECTRUST and the native Apple trust store is in use, a certificate that OpenSSL/GnuTLS rejects because it is on the operator's CURLOPTCRLFILE list is re-checked by Apple's SecTrust API instead, and SecTrust is never told about that CRL file at all. The bug...

OCSP Response Validation Bypass

Bouncy Castle for Java is vulnerable to an OCSP response validation bypass. The vulnerability is due to the failure to properly associate the stapled OCSP response with the intended certificate, which allows an attacker to exploit the validation process by providing a valid OCSP response for a...

rustls-webpki: rustls-webpki: Denial of Service via crafted Certificate Revocation List

A flaw was found in rustls-webpki. A remote attacker, by influencing an application to parse a specially crafted Certificate Revocation List CRL that contains an empty onlySomeReasons value in its issuingDistributionPoint extension, could trigger a panic. This vulnerability leads to a denial of...

PYSEC-2026-3676 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,...
