    CVE-2026-12151

    undici WebSocket client vulnerable to denial of service via fragment count bypass

    Impact: The undici WebSocket client enforces maxPayloadSize on the cumulative byte count of fragments in a message but does not enforce a limit on the number of fragments. A malicious WebSocket server can stream many small or empty continuation frames that ea…

    CVE-2026-59869

    js-yaml: YAML merge-key chains can force quadratic CPU consumption

    js-yaml is a JavaScript YAML parser and dumper. From 3.0.0 before 3.15.0 and from 4.0.0 before 4.3.0, js-yaml can spend quadratic CPU time parsing a document whose size grows only linearly when a chain of mappings uses merge keys where each mapping merges the…

    CVE-2026-6734

    undici vulnerable to cross-origin request routing via SOCKS5 proxy pool reuse

    Impact: When using Socks5ProxyAgent, undici reuses a single connection pool across different origins without verifying that the pool's origin matches the requested origin. All requests are dispatched through the pool connected to the first origin, regardless …

    CVE-2026-9697

    undici vulnerable to TLS certificate validation bypass via dropped requestTls in SOCKS5 ProxyAgent

    Impact: undici's ProxyAgent silently drops the requestTls option when configured with a SOCKS5 proxy URI (socks5:// or socks://). The target HTTPS connection through the SOCKS5 tunnel falls back to Node's default trust store, ignoring user-configured ca, cert…

    CVE-2026-9678

    undici vulnerable to cross-user information disclosure via shared cache whitespace bypass

    Impact: Undici's cache interceptor incorrectly classifies some responses as cacheable when the upstream Cache-Control header uses whitespace-padded qualified private or no-cache field names such as private=" authorization" or no-cache="\tauthorization". The p…

    CVE-2026-9679

    undici vulnerable to HTTP header injection via Set-Cookie percent-decoding

    Impact: undici's cookie parser in parseSetCookie percent-decodes cookie values via qsUnescape, turning encoded sequences like %0D%0A, %00, %3B, and %3D into their literal byte equivalents. RFC 6265 §5.4 does not specify any decoding and browsers do not decode…

    morgan vulnerable to Log Forging via unneutralized control characters in :remote-user

    Impact: The morgan logging middleware's :remote-user token extracts the Basic auth username from the Authorization request header and writes it to the log stream without neutralizing control characters. An unauthenticated attacker can send a crafted Authoriza…

    js-yaml: Quadratic-complexity DoS in merge key handling via repeated aliases

    js-yaml is a JavaScript YAML parser and dumper. Prior to 4.2.0 and 3.15.0, a crafted YAML document can trigger algorithmic CPU exhaustion in js-yaml merge-key processing (<<) by repeating the same alias many times in a merge sequence. This causes quadratic pa…

    undici vulnerable to Set-Cookie SameSite attribute downgrade via permissive substring matching

    Impact: When undici parses a Set-Cookie header, it accepts any SameSite attribute value that contains Strict, Lax, or None as a substring, rather than the case-insensitive exact match specified by RFC 6265. Non-spec values are silently mapped to one of the th…

    undici vulnerable to HTTP response queue poisoning via keep-alive socket reuse

    Impact: Undici's HTTP/1.1 client is vulnerable to response queue poisoning on reused keep-alive sockets. An attacker-controlled upstream server can inject an unsolicited HTTP/1.1 response onto an idle socket after a request completes. When the client dispatch…
