GHSA-FWJX-9P69-H25H Oh My Posh: Terminal escape sequence injection via unsanitized prompt segment data

Summary Oh My Posh renders dynamic, potentially attacker-controlled strings the current directory name, Git commit metadata, environment variable values, command output into the prompt without neutralizing raw terminal control characters. An attacker who controls one of these values can inject...

Improper Authentication

Overview Affected versions of this package are vulnerable to Improper Authentication in the authentication process when handling OIDC subject identifiers due to the use of an accent-insensitive collation in the database. An attacker can gain unauthorized access to another user's account by...

GHSA-CMWH-G2H8-C222 Poweradmin: OIDC `sub` collation bypass in Poweradmin leading to account takeover

Preface Poweradmin maps OIDC identities into local users through oidcuserlinks.oidcsubject plus providerid. In the MySQL schema, the OIDC link table explicitly uses utf8mb4unicodeci, which is case-insensitive and accent-insensitive. OIDC sub is a stable external subject identifier and should be...

Out-of-bounds Read

Overview apple/swift-nio-ssl is a TLS Support for SwiftNIO, based on BoringSSL. Affected versions of this package are vulnerable to Out-of-bounds Read due to improper handling of the NIOSSLCertificate.subjectAlternativeNames process. An attacker can cause out-of-bounds memory access by accessing...

CVE-2026-43820

NIOSSLCertificate.subjectAlternativeNames provides access to the raw bytes for a cert's SANs. NIOSSL provides access to a buffer assumed to be backed by an ASN1STRING, but not all SANs are backed by ASN1STRING, so accessing the buffer for such a type can lead to out-of-bounds memory access. This...

n8n: Cross-Issuer Token Exchange Account Binding via Subject-Only Identity Resolution

Impact When an n8n instance is configured with more than one trusted token-exchange issuer, external identities are resolved to local accounts using only the JWT sub claim, ignoring the issuer iss. As a result, two different issuers that emit the same subject value map to the same local account. ...

gnutls: gnutls: Certificate validation bypass due to oversized Subject Alternative Name

A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name SAN could cause the validation process to incorrectly fall back to checking the Common Name CN field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to...
