A heap use-after-free exists in wolfSSL's TLS 1.3 post-quantum cryptography PQC hybrid KeyShare processing. In the error handling path of TLSXKeyShareProcessPqcHybridClient in src/tls.c, the inner function TLSXKeyShareProcessPqcClientex frees a KyberKey object upon encountering an error. The call...

JLSEC-2026-683 An issue was discovered in wolfSSL before 5.7.0

An issue was discovered in wolfSSL before 5.7.0. A safe-error attack via Rowhammer, namely FAULT+PROBE, leads to ECDSA key disclosure. When WOLFSSLCHECKSIGFAULTS is used in signing operations with private ECC keys, such as in server-side TLS connections, the connection is halted if any fault...

JLSEC-2026-706 Out-of-bounds read in ALPN parsing due to incomplete validation

Out-of-bounds read in ALPN parsing due to incomplete validation. wolfSSL 5.8.4 and earlier contained an out-of-bounds read in ALPN handling when built with ALPN enabled HAVEALPN / --enable-alpn. A crafted ALPN protocol list could trigger an out-of-bounds read, leading to a potential process crash...

CVE-2026-48038

joi is a schema description language and data validator for JavaScript. Prior to 17.13.4 and 18.2.1, denial of service is possible via an untrapped exception in services validating user-supplied JSON or object input with recursive link schemas. When validate is called without try/catch in a reque...

CVE-2026-48038 joi: Uncaught RangeError on deeply nested input through recursive `link()` schemas

joi is a schema description language and data validator for JavaScript. Prior to 17.13.4 and 18.2.1, denial of service is possible via an untrapped exception in services validating user-supplied JSON or object input with recursive link schemas.

CVE-2026-48038

Joi (JavaScript) vulnerability CVE-2026-48038: In versions prior to 17.13.4 and 18.2.1, validation of deeply nested user input via recursive link() schemas can trigger an unhandled RangeError when validate() runs without try/catch, potentially crashing the process. Fixed in 17.13.4 and 18.2.1. CV...

CVE-2026-48784 Symfony: UrlGenerator Dot-Segment Encoding Skips Every Other Chained `../` or `./` → Generated URL Collapses Off-Route Under RFC 3986 Normalization

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.53, 6.4.41, 7.4.13, and 8.0.13, UrlGenerator::doGenerate used strtr dot-segment encoding that skipped every other chained ../ or ./ segment, allowing attacker-controlled route parameters...

CVE-2026-15712

CVE-2026-15712 affects libsoup’s HTTP/2 connection tracking in/libsoup3 (versions 3.0–3.7.0) where the GOAWAY frame’s Additional Debug Data is parsed as a NUL-terminated C-string without strict length checks. This permits a remote, unauthenticated attacker to send malformed GOAWAY frames, causing...

UBUNTU-CVE-2026-59884

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets without an upper bound on the tag ID size, allowing a crafted input to force construction of an arbitrarily large integer with C...
