EUVD-2026-41425

Pathway through 0.31.1, fixed in commit d09722e, document store applies a caller-supplied glob pattern to indexed document paths using a hand-written recursive matcher that branches two ways on each token without memoization, giving exponential worst-case complexity. The filepathglobpattern value...

eclipse-vertx/vert.x: eclipse-vertx/vert.x: Denial of Service via TLS handshake with wildcard server name

A flaw was found in eclipse-vertx/vert.x. A remote attacker can exploit this vulnerability by performing a Transport Layer Security TLS handshake and presenting a server name extension with a server wildcard name. This can lead to a denial of service DoS condition, impacting the availability of t...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

CVE-2026-57231

Podman is a tool for managing OCI containers and pods. From 1.8.1 until 5.8.4, a container image that contains a environment variable with just a key and no value can trick podman into passing that variable from the host into the container. This is made worse by the fact that using an asterisk wi...

CVE-2026-57231

CVE-2026-57231 affects Podman versions 1.8.1 through 5.8.4, where a container image with an Env entry having only a key (and using the * wildcard) can cause host environment variables to be leaked into the container at run time. The PTSecurity document confirms the issue is addressed in Podman 5....
