GHSA-9GM5-9RFH-M6VX CoreDNS DoH/DoQ/gRPC bypass UPDATE rejection enforced on UDP/TCP

Summary CoreDNS accepted RFC 2136 UPDATE messages over DoH, DoH3, DoQ, and DNS-over-gRPC, then allowed the proxy/forward plugin to send them unchanged to an upstream DNS server. UDP, TCP, and DoT rejected the same opcode before plugin dispatch. If an update-capable upstream trusts CoreDNS's sourc...

GHSA-GJV8-XP57-G29C Soup Sieve: Polynomial-time ReDoS (O(n²)) in the `IDENTIFIER` / `VALUE` selector sub-patterns

Summary soupsieve compiles CSS selector strings with a set of hand-written regular expressions. The shared IDENTIFIER sub-pattern also embedded in VALUE, and therefore in attribute selectors places two adjacent quantified groups over overlapping character classes: ?:classA|ESC+?:classB|ESC, where...

GHSA-J934-XHV5-FG8F Soup Sieve: Polynomial-time ReDoS (O(n²)) in the whitespace/comment trimming regex `RE_WS_END` (triggers on VALID selectors)

Summary Before tokenizing, selectoriter trims leading/trailing whitespace and comments by running two regexes over the whole raw selector with .search. The trailing one, REWSEND = re.compiler'WSC$', is anchored only at the end $, not the start. Because .search retries the pattern at every offset,...

GHSA-QRFJ-MGW8-J9C6 @platejs/core HTML deserialization can trigger browser behavior during parsing

Summary HTML strings passed to Plate's core deserialization APIs were parsed in the active document. Certain HTML attributes could therefore trigger browser behavior during parsing, before the content was converted into editor nodes. Applications that deserialize HTML from untrusted or cross-user...

GHSA-X424-64QH-5J54 react/http: A malformed HTTP chunked body can lead to a denial-of-service and peg the CPU

Summary A malformed HTTP message using Transfer-Encoding: chunked can drive React\Http\Io\ChunkedDecoder into an infinite loop, pegging a CPU core and freezing the event loop. Because ReactPHP is single-threaded, one such message stalls the entire process for every client until it is killed. Both...

GHSA-MRG3-QVQR-JW29 CoreDNS: Unauthenticated memory exhaustion in custom transports

Summary CoreDNS parses attacker-controlled DNS section counts before validating them on DNS-over-HTTPS DoH and DoH3, DNS-over-QUIC DoQ, and DNS-over-gRPC listeners. An unauthenticated client can use DNS name compression to make one 65,533-byte request allocate more than 10 MiB while it is unpacke...

GHSA-3W98-RRPR-FPRR HAPI FHIR: SHCParser unbounded DEFLATE decompression causes denial of service

Summary SHCParser inflates compressed Smart Health Card JWT payloads into memory without a decompressed-size limit. An attacker who can submit SHC content for validation can craft a small compressed JWT payload that expands to a very large byte array, causing memory exhaustion or severe garbage...

GHSA-W34Q-CM8F-9C5X OpenTelemetry-Go: Log gRPC exporter ignores env TLS certs, bypassing mTLS/pinning

Summary The OTLP log gRPC exporter loads TLS settings from environment variables but does not apply them when creating gRPC transport credentials.

GHSA-C3MW-737P-C7G2 Jupyter Server: 5xx request logging leaks token-bearing Referer header values

Summary When a request returns a 500, jupyterserver/log.py logs a small JSON block of request headers. The Referer header was copied into it as-is, so a token in the Referer URL ended up in the logs in plain text. Impact Anyone who can read the server logs can pick tokens out of these 500 entries...

GHSA-3JHR-MXMX-38CX Grav: UserInterface offsetget/offsetexists allow-listed in Twig sandbox let editor-authored content leak hashed_password and 2FA secrets via offsetGet()

Summary system/config/security.yaml's Twig sandbox policy allow-lists offsetget and offsetexists for Grav\Common\User\Interfaces\UserInterface. The concrete Grav\Common\User\DataUser\User class does not filter which fields offsetGet returns, so any sandboxed template with access to a User object...

GHSA-38P6-H87P-R4CG Grav: Non constant time nonce comparison in Utils::verifyNonce() used for CSRF protection

Summary Grav\Common\Utils::verifyNonce, the core function Grav and its plugins use to validate CSRF nonces, compares the submitted nonce to the expected value with PHP's === operator instead of hashequals. === on strings short circuits at the first differing byte, so the comparison time leaks how...

GHSA-4RF6-QX84-Q9FV Fulgur: Non-painting replaced elements amplify to thousands of blank PDF pages (denial of service)

fulgur converts untrusted HTML/CSS into PDF, commonly on a server that processes input supplied by many tenants.

GHSA-F8M2-889X-VW4X AsyncHttpClient re-sends client-wide realm credentials to a cross-origin redirect target

Impact A client configured with a client-wide realm a Realm set on the config builder rather than on an individual request and following redirects could re-send those credentials to a redirect target on a different origin. The redirect code strips the per-exchange realm, but when the target...

GHSA-XR57-GCX8-52HF AsyncHttpClient sends origin credentials to the proxy on the plaintext CONNECT request

Impact When a request uses an HTTP proxy to reach an HTTPS origin, the client opens the tunnel with a plaintext CONNECT sent to the proxy before any TLS exists. On affected versions the origin's preemptive credentials were added to that CONNECT. A Basic realm sent Authorization: Basic...

GHSA-7GRG-JCF7-RPMX AsyncHttpClient's unbounded HTTP/1.1 response decompression enables a decompression-bomb denial of service

Impact With automatic response decompression enabled the default, the HTTP/1.1 path decompresses response bodies with no limit on the total output size. A hostile or compromised server, or an attacker who can change a response in transit, can send a small compressed body that inflates without bou...

GHSA-FJ9W-C36G-H5X8 AsyncHttpClient doesn't verify SCRAM and Digest mutual-authentication responses

Impact For SCRAM, and for Digest with mutual authentication, the client computes the server's verification value the SCRAM ServerSignature, or the Digest rspauth but does not act on the result. If the value is present and does not verify, the client only logs it and still delivers the response to...

GHSA-MGGC-4XG6-VCXF SSH.NET: ScpClient allows server-side RCE via default SCP path handling

Summary Default SCP remote-path handling places caller-supplied paths into the command that runs scp on the server. On a shell-based server that command is interpreted by a shell, so an attacker-influenced path that is not quoted to suit that shell can execute as a command as the authenticated SS...

GHSA-HPJ9-GRJP-7VC7 Kestra: Unauthenticated management/actuator endpoints exposed on port 8081 (/env, /loggers) bypass API basic-auth

Summary Kestra's Micronaut management endpoints are served on port 8081 with no authentication, even when the main API port 8080 has basic-auth enabled. Anyone who can reach :8081 can read GET /env full resolved environment/configuration and mutate runtime state via POST /loggers/name change log...
