fast-uri vulnerable to host confusion via failed IDN canonicalization
Impact fast-uri versions = 2.3.1, = 4.0.0 fail to canonicalize Unicode/IDN hostnames for HTTP-family URLs. The IDN conversion path calls URL.domainToASCII... on the global WHATWG URL constructor, where that helper does not exist. The resulting TypeError is silently routed into parsed.error, but...
Immutable: Hash-collision algorithmic complexity denial of service in Immutable.Map/Set
Summary Immutable.Map and Immutable.Set keep keys that share the same 32-bit hash in a collision bucket that is scanned linearly. The string hash is public and deterministic, so an attacker who controls the keys inserted into a Map can craft many keys that all collide, degrading insertion and...
Immutable.js `List` 32-bit trie overflow → unrecoverable DoS
Summary Listset, ListsetSize, ListsetIn, ListupdateIn and the functional set / setIn / updateIn mishandle an index or size in the range 2 30, 2 31: - On an empty List the operation enters an uncatchable infinite loop a tight CPU spin; a surrounding try/catch never regains control. Only killing th...
guzzlehttp/psr7: Host Confusion via Weak URI Host Validation
Impact guzzlehttp/psr7 did not reject URI host components containing authority delimiters /, ?, , @, or , an embedded port such as host:8080, or IPv6 brackets that do not frame the host such as ::1 or ::1. Uri::assertValidHost rejected only control characters, so these malformed hosts were...
websocket-driver-ruby: Denial of service via malformed Host header
Impact If this library is used to implement a WebSocket server on top of a TCP server, by using the WebSocket::Driver.server method, then a client can cause the server to crash by sending a Host header that is not a valid host:port string. When this happens, a URI::InvalidURIError exception is...
hono/jsx does not isolate context per request, leading to cross-request data disclosure
Summary hono/jsx did not isolate context values per request during server-side rendering. While an async component was suspended on await, its provided context value stayed observable to other requests rendering concurrently, so useContext could return a value from a different in-flight request...
Hono: Server-Side XSS via JSX Escaping Bypass in cx() Utility
Summary cx in hono/css composes class names from plain strings but marks the result as already-escaped without HTML-escaping the input. When the result is used as a JSX class attribute during server-side rendering, the value is written into the attribute unescaped, so untrusted input can break ou...

Guzzle: Host-only cookie scope is not preserved
Impact In affected versions, CookieJar does not preserve whether a response cookie was set without a Domain attribute or with an empty one. A cookie without Domain is host-only and must be returned only to the exact host that set it. Under current cookie processing rules, an empty Domain value is...
Guzzle: Unbounded response cookies risk denial of service
Impact In affected versions, Guzzle's built-in CookieJar accepts any number of Set-Cookie header fields from one response, with no limit on the size of each field. When a later request matches the stored cookies, Guzzle places every match into one generated Cookie header without limiting the numb...
Astro: composable `astro/hono` pipeline bypasses `security.checkOrigin` when `middleware()` is absent or misordered
Summary In the composable astro/hono pipeline, the security.checkOrigin protection is only installed by the middleware primitive. The actions and pages primitives each dispatch to user code independently, so a pipeline that mounts either primitive before or without middleware will bypass the orig...
Astro: Unauthenticated path override in the @astrojs/vercel ISR function
Summary When ISR is enabled, the serverless entrypoint lets an unauthenticated request decide which route the origin renders. The internal isr function reads the xastropath query parameter and rewrites the request path to it without any authentication. Edge level access controls only ever see the...
@astrojs/netlify generates an overly-broad Netlify Image CDN allowlist because remotePatterns.pathname metacharacters are not escaped
Summary The @astrojs/netlify adapter converts each image.remotePatterns entry into a regular expression that is written to .netlify/v1/config.json under images.remoteimages. Netlify's Image CDN uses these regexes as the allowlist that decides which remote image URLs it will optimize...
body-parser vulnerable to denial of service when invalid limit value silently disables size enforcement
Impact When body-parser is configured with an invalid limit option value, such as an unparseable string or NaN, bytes.parse returns null and the request body size check is silently skipped. Applications that rely on limit as their primary safeguard against oversized request bodies will accept...
@astrojs/node: Backslash-prefixed paths not recognized as internal by trailing-slash redirect
Impact With trailingSlash: 'always' configured, the @astrojs/node standalone server's static file handler appends a trailing slash to request paths and issues a 301 redirect. Paths beginning with /\ slash-backslash were not recognized as internal paths, so the handler would echo the raw path back...

Pillow JPEG2000 tiled decode retains a growing scratch buffer and can be used for denial of service
Summary src/libImaging/Jpeg2KDecode.c:853 accumulates totalcomponentwidth across every tile in a JPEG2000 image instead of recomputing it per tile. That accumulated value is then used in the tilebytes calculation at src/libImaging/Jpeg2KDecode.c:868, which can make the decoder grow state-buffer v...
Pillow EpsImagePlugin negative %%BeginBinary byte count causes infinite loop denial of service
Summary Pillow's EPS parser PIL/EpsImagePlugin.py accepts a negative byte count in the %%BeginBinary directive. A crafted EPS file can cause Image.open to seek backwards to the same directive and parse it repeatedly, resulting in an infinite loop and CPU denial of service. The issue is triggered...
Pillow: Decompression Bomb DoS via PdfParser.PdfStream.decode()
Summary PdfParser.PdfStream.decode in Pillow's PdfParser.py calls zlib.decompress with the bufsize parameter set to the value of the PDF stream's Length field, without any upper bound on the actual decompressed output size. Python's zlib.decompress bufsize argument is an initial output buffer hin...
Pillow: Heap out-of-bounds write `Image.paste()` / `Image.crop()` via signed coordinate overflow
Summary Pillow's public image coordinate APIs can trigger a native heap out-of-bounds write when given coordinates near the signed 32-bit integer limits. In 4-byte pixel modes such as RGBA, this becomes a controlled backward heap underwrite: for a source image of width W, Pillow writes 4 W...
Pillow TGA RLE encoder can serialize up to ~57 KB of adjacent heap data into generated images
Summary Pillow's TGA RLE encoder reads past its row buffer when saving a mode "1" image. Adjacent process heap bytes can be copied into the generated TGA file. The bug is reachable through the public save API: python im.saveout, format="TGA", compression="tgarle" Older affected Pillow versions us...
Pillow: Heap out-of-bounds write in `ImageFilter.RankFilter` via integer overflow in `ImagingExpand`
