activestorage: Active Storage: Denial of Service via thread exhaustion from streaming storage errors

### Impact When Active Storage serves a file through its proxy controllers, `ActiveStorage::Streaming#send_blob_stream` handles an error from the storage service by calling `head` to send a 404 or 500 response. If the error occurs after the first chunk has been written, the response is already committed, and `head` replaces the response body while the server is still reading the original `ActionController::Live` buffer. That buffer is never closed, so the server thread…

actionmailbox: Action Mailbox: Inbound email forgery via Mailgun webhook signature replay

### Impact The Action Mailbox Mailgun ingress authenticates a request with an HMAC of the `timestamp` and `token` parameters concatenated without a separator, and `ActionMailbox::Ingresses::Mailgun::InboundEmailsController::Authenticator#recent?` rejects only timestamps more than 2 minutes in the past. Because the signature does not fix the boundary between the two values, a captured signed request can be presented with a timestamp far in the future, which the ingress then…

actionpack: Action Pack: Cross-Site Request Forgery via missing SameSite attribute on session cookies

### Impact Action Pack session stores other than `ActionDispatch::Session::CookieStore` (`CacheStore`, `MemCacheStore`, and third-party stores built on `AbstractStore`, `AbstractSecureStore` or the session mixins) write the session cookie without a `SameSite` attribute, regardless of `config.action_dispatch.cookies_same_site_protection`, which defaults to `:lax`. Only `CookieStore` applies the configured policy. In browsers that do not treat a cookie without the attribute as…

fast-xml-parser: fast-xml-parser: Denial of Service via quadratic rescanning of unterminated tags

### Summary With the non-default stopNodes option, a stop node's body with many " " anywhere after makes readStopNodeData() rescan the entire remaining input from every " ` exists - `OrderedObjParser.js:812-818` — on failure, `i` isn't advanced, so the next ` ` lookahead is neither cached nor bounded — `n` copies of ` ` means `n` scans over the remaining input, O(n²) work, before it finally throws. **Fix** 1. Throw immediately in `readStopNodeData()` when `readTagExp()`…

nokogiri: nokogiri: Denial of Service via use-after-free when replacing attribute values

### Summary Nokogiri's CRuby native extension could leave a Ruby wrapper pointing to freed memory when replacing the value of an existing XML attribute via `Nokogiri::XML::Node#[]=` or `Nokogiri::XML::Node#lang=`. If Ruby code had already accessed the attribute's child nodes, replacing the value could free those native child nodes while their wrappers remained reachable. Using one of those child nodes afterwards could cause an invalid read and a possible segfault. This is…

nokogiri: nokogiri: Server-Side Request Forgery via network restriction bypass on JRuby

### Summary On JRuby, the `NONET` parse option did not block an external DTD or entity whose system identifier used a short-form IPv4 host, such as `http://127.1/` or `http://169.254.43518/`, or was an absolute path such as `/x.dtd` in a document parsed from a network URL. An application that parses untrusted XML with `DTDLOAD`, `DTDVALID` or `NOENT` could be made to send network requests, potentially enabling SSRF. Nokogiri 1.19.5 applies the `XML::Schema` check from…

node-forge: node-forge: Signature verification bypass via unvalidated small-order Ed25519 public keys

### Summary `ed25519.verify()` does not reject public keys of small order, such as the identity point. Under such a key, a signature with `S = 0` and a small-order `R` verifies for many messages, or for every message with the identity key, without any private key. Fixed in node-forge 1.4.3. ### Details `crypto_sign_open()` in `lib/ed25519.js` decodes the public key `A` with `unpackneg()`, which only checks that the point is on the curve, and then checks `R == [S]B - [k]A`…

node-forge: node-forge: Denial of Service via inefficient regular expression in HTTP header parsing

`forge.http` trims response header and `Set-Cookie` values with the regular expression `/\s*$/`, which takes quadratic time on a long run of whitespace followed by another character. A server or on-path attacker can block a `forge.http` client for minutes with one large response header. Fixed in node-forge 1.4.3. ### Details `_trimString()` in `lib/http.js` removes trailing whitespace with `str.replace(/\s*$/, '')`. On a string of n whitespace characters followed by a…

node-forge: node-forge: Denial of Service via unsupported TLS ServerHello compression method

### Summary A `forge.tls` client accepts any compression method in the ServerHello, although it only offers no compression. An unknown method makes `connection.process()` throw an uncaught `Error` when the client handles ServerHelloDone, before the server is authenticated. A malicious server or an on-path attacker can use this to terminate a Node.js process. Fixed in node-forge 1.4.3. ### Details The client's ClientHello offers only the `null` compression method…
