GHSA-V5MV-P594-2X33 Guzzle: Noncanonical host can bypass host-based checks

Impact In affected versions, Guzzle gives a transport the request URI as text and supplies the Host header separately. The cURL handlers set CURLOPTURL to the URI exactly as written and push that Host into CURLOPTHTTPHEADER; StreamHandler does the same through fopen. libcurl then parses the...

GHSA-F7VP-7XGX-4W4R Guzzle: Noncanonical cookie domain keeps subdomain scope

Impact SetCookie::matchesDomain gives every subdomain of a cookie Domain that cookie unless it recognizes the Domain as an IP literal or a numeric host, and it decides that from the domain's own text, so two spellings a transport reads as an address keep subdomain scope. On 7.15, hexadecimal and...

GHSA-CQ5V-8Q36-5273 AIOHTTP: Out-of-bounds heap read in C HTTP response parser error path (malformed chunked response)

Summary An out-of-bounds heap read could occur in the C response parser while building an error message for a malformed response. Impact An attacker controlled server, or possibly an accidental response could trigger a DoS in the client. Workaround If unable to upgrade, the Python parser is...

GHSA-MWP4-54F8-5FHR ip-address: Address4 decodes leading-zero octets as decimal while resolvers decode them as octal, allowing SSRF and trust-boundary bypass

Summary Address4 accepts an octet written with a leading zero and decodes it as decimal, while the WHATWG URL host parser, inetaton, and getaddrinfo all decode a leading zero as octal. The library and the network stack therefore disagree about which host a string names. new Address4'012.0.0.1'...

GHSA-4XRF-JV44-H6HH ip-address: a CIDR suffix on the parsed address suppresses special-use classification and can bypass SSRF and trust-boundary checks

Summary Every special-use classification method is built on isInSubnet, which short-circuits to false whenever the address's own subnet mask is shorter than the reference range's mask. That mask comes verbatim from the CIDR suffix on the parsed input, so appending a suffix such as /0 suppresses...

GHSA-22JQ-VG5J-6VGG ip-address: misclassification of IPv4-mapped/NAT64 IPv6 addresses can bypass SSRF and trust-boundary checks

Summary Address6's special-property checks misclassify IPv4-mapped ::ffff:0:0/96 and NAT64 well-known 64:ff9b::/96 IPv6 addresses. These checks classify an address by its IPv6 wrapper rather than by the IPv4 address it embeds, so isLoopback, isLinkLocal, isMulticast, and isUnspecified all return...

GHSA-M8RV-5G2X-5CG5 undici vulnerable to CRLF Injection via blob-like body 'type' property

Impact When an application passes a duck-typed blob-like body to undici's HTTP/1.1 dispatcher via request, stream, pipeline, or dispatch with a .type derived from untrusted input, an attacker can inject CRLF sequences \r\n to append arbitrary HTTP headers and potentially smuggle a second request...

GHSA-JR45-8VMC-QM54 undici vulnerable to cross-user information disclosure via whitespace around equals in Cache-Control directives

Impact Undici's cache interceptor mishandles optional whitespace OWS placed around the = of a qualified no-cache or private Cache-Control directive, such as no-cache ="authorization" OWS before = or no-cache= "authorization" OWS after =. The parser either drops the directive entirely or stores a...

GHSA-V3R7-H72X-CJCM undici vulnerable to cookie attribute injection via unsanitized domain and unparsed setCookie fields

Impact The setCookie function has two attribute injection paths. validateCookieDomain does not reject semicolons validateCookiePath already does at 0x3B, so a domain value like example.com; SameSite=None lands verbatim as Domain=example.com; SameSite=None. The unparsed array's loop only checks ea...

GHSA-8XCM-R25X-G524 undici vulnerable to downstream response desynchronization via retry interceptor

Impact Undici's interceptors.retry can deliver a response whose body length does not match the Content-Length header exposed to the application after a retry or resume of a partial response. Applications that use interceptors.retry and forward upstream response headers and bodies downstream, for...

GHSA-FXQJ-RQCC-2CMP PostCSS: incomplete fix of GHSA-6g55-p6wh-862q — attacker-controlled sourceMappingURL reads arbitrary .map files when `from` is unset

Summary The fix for GHSA-6g55-p6wh-862q added a guard in lib/previous-map.js PreviousMap.loadFile that restricts an attacker-controlled sourceMappingURL from a CSS comment to a .map extension and, for untrusted maps, rejects .. traversal and absolute paths. The traversal/absolute rejection is...

GHSA-RGW5-RVV9-X895 brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation

Summary The maxLength mitigation added in 5.0.8 for GHSA-mh99-v99m-4gvg / CVE-2026-14257 is incomplete. It bounds the accumulator where results are combined, but not the intermediate arrays that feed it. A 25 KB input still crashes the Node process with an uncatchable out-of-memory error, so...
