gnutls: gnutls: Authentication Bypass via NUL Character in Username

A flaw was found in gnutls. Servers configured with RSA-PSK Rivest–Shamir–Adleman – Pre-Shared Key wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass...

gnutls: gnutls: Information disclosure via heap overread in RSA key exchange

A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure...

libxslt: use-after-free with key data stored cross-RVT

A use-after-free vulnerability was found in libxslt while parsing xsl nodes that may lead to the dereference of expired pointers and application crash...

CVE-2026-6291

Bleichenbacher padding oracle in PKCS7 KTRI decryption. When decrypting PKCS7 EnvelopedData using RSA PKCS1 v1.5 key transport, wolfSSL returned distinguishable error codes depending on whether RSA padding validation failed versus whether the decrypted content was malformed. An attacker able to...

GHSA-2933-Q333-QG83 i18next-fs-backend vulnerable to prototype pollution via crafted missing-key string

Impact i18next-fs-backend ≤ 2.6.5, when used to persist missing translation keys e.g. via i18next-http-middleware's missingKeyHandler exposed to untrusted input, is vulnerable to prototype pollution via crafted missing-key strings. Backend.writeFile splits each queued missing-key string on the...

i18next-http-middleware: MissingKeyHandler does not reject keys whose segments contain prototype-polluting names

Impact i18next-http-middleware ≤ 3.9.6's missingKeyHandler blocked the literal request-body keys proto, constructor, and prototype added in 3.9.3, see GHSA-5fgg-jcpf-8jjw, but did not reject dotted variants such as "proto.polluted". Downstream backends that split the missing-key string on a...

Authorization Bypass Through User-Controlled Key

Overview Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key in the token-read process. An attacker can generate unauthorized OAuth2 bearer tokens with arbitrary user, client, realm, and scope values by injecting attacker-controlled JSON into the...

CVE-2026-55961 wolfSSL_PKCS7_verify() reports success for degenerate (certs-only) PKCS#7 with no signer

wolfSSLPKCS7verify returning success for a degenerate certs-only PKCS7 object that contains no signer. Such an object has empty signerInfos, so the underlying signed-data verification succeeds without authenticating any content. The compatibility-layer verify path now rejects the object when no...

CVE-2026-55699

pnpm is a package manager. Prior to 10.34.2 and 11.5.3, Manifest bin object keys such as "", ".", and ".." passed pnpm's bin-name guard. When a malicious package was installed globally, later global remove, update, or add-replacement flows could re-derive those names from the installed manifest a...
