undici: undici: Denial of Service due to unbounded memory growth via WebSocket frames

A flaw was found in undici. A malicious WebSocket server can exploit this by streaming numerous small or empty continuation frames. This can bypass per-frame and cumulative-size validation, leading to unbounded memory growth in the client process. The primary consequence is memory exhaustion,...

Security Bulletin: Vulnerability in undici bundled with IBM Fusion, IBM Fusion HCI, and IBM Fusion Content-Aware Storage

Summary IBM Fusion, IBM Fusion HCI, and IBM Fusion Content-Aware Storage include the undici library, which is affected by a denial of service vulnerability. CVE-2026-22036 Vulnerability Details CVEID:CVE-2026-22036 DESCRIPTION: Undici is an HTTP/1.1 client for Node.js. Prior to 7.18.0 and 6.23.0,...

undici: Undici: Response queue poisoning on reused keep-alive sockets can lead to incorrect response delivery.

A flaw was found in undici. An attacker-controlled upstream server can exploit a vulnerability in Undici's HTTP/1.1 client, specifically related to response queue poisoning on reused keep-alive sockets. This allows the attacker to inject an unsolicited HTTP/1.1 response onto an idle socket...

undici: Undici: Information disclosure due to improper cache-control header parsing

A flaw was found in Undici. The cache interceptor in shared-cache mode incorrectly classifies certain responses as cacheable due to improper handling of whitespace-padded Cache-Control header field names. This vulnerability allows an unauthenticated attacker to access authenticated user data from...

undici: undici: Weakening of cookie SameSite policy due to incorrect parsing of Set-Cookie header

A flaw was found in undici. When undici processes Set-Cookie headers, it incorrectly interprets the SameSite attribute, accepting partial matches instead of exact ones. This allows a malicious server to downgrade a cookie's SameSite policy to a less secure setting, potentially leading to unintend...

Linux Distros Unpatched Vulnerability : CVE-2026-9697

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Impact: undici's ProxyAgent silently drops the requestTls option when configured with a SOCKS5 proxy URI socks5:// or socks://. The target HTTPS connection...

Linux Distros Unpatched Vulnerability : CVE-2026-9675

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Impact: The undici WebSocket client enforces maxPayloadSize per-frame but does not enforce the cumulative size of fragmented uncompressed messages. A malicious...

Linux Distros Unpatched Vulnerability : CVE-2026-11525

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

Linux Distros Unpatched Vulnerability : CVE-2026-9679

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Impact: undici's cookie parser in parseSetCookie percent-decodes cookie values via qsUnescape, turning encoded sequences like %0D%0A, %00, %3B, and %3D into the...

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 three standard tokens: -...
