Incorrect Ed25519 public key validation

!NOTE The fix was released in v2.5.1 Reported by Arpit Jain @arpitjain099 via email. This validation gate misfires, allowing invalid public keys to be loaded. Full advisory: https://github.com/paragonie/sodiumcompat/security/advisories/GHSA-733q-f2wq-9c8w The actual downstream impact is minimal i...

Client HttpTransport SSE buffer grows unbounded when server withholds the event delimiter

Summary The HTTP client transport in mcp/sdk reads a Server-Sent-Events SSE response stream incrementally and appends each 4 KiB chunk to an in-memory buffer $this-sseBuffer .= $chunk; with no upper bound. The buffer is only ever flushed when an SSE event delimiter "\n\n" appears. A remote MCP...

Custom action dispatcher bypasses access_control on other routes

Summary EasyAdmin serves all backend requests through a single dashboard route and, for custom actions Action::linkToRoute / MenuItem::linkToRoute, swaps the executed controller based on the routeName query parameter on the kernel.controller event. That swap happens after Symfony's security...

OS Command injection

Impact PHPCodeSniffer versions before v3.13.6 and v4.0.2 contain a command injection vulnerability in the code creating the Gitblame, Hgblame and Svnblame reports. As a result, running PHPCodeSniffer over untrusted files, for example, in a CI pipeline that scans pull requests, or on a developer...

Arbitrary code execution

Impact WordPress Coding Standards WordPressCS versions before 3.4.1 contain an arbitrary code execution vulnerability in the WordPress.WP.EnqueuedResourceParameters sniff. As a result, running PHPCS with WordPressCS over untrusted PHP code, for example, in a CI pipeline that lints pull requests, ...

Arbitrary code execution

Impact PHPCSUtils versions 1.0.0-alpha1 through 1.2.2 contain an arbitrary code execution vulnerability in PHPCSUtils\AbstractSniffs\AbstractArrayDeclarationSniff::getActualArrayKey. The vulnerable method is reached by any sniff that extends AbstractArrayDeclarationSniff and calls...

symfony/ux-toolkit Path Traversal allows arbitrary file write and read via crafted recipe manifest

Description The ux:install console command installs files from a recipe kit by copying paths listed in a copy-files map. The only guard against malicious paths was Path::isRelative, which returns true for paths like ../../../etc. Path::join then resolves the .. segments without complaint, so the...

symfony/ux-icons XSS via unsanitized SVG content in local files and Iconify on-demand responses

Description The uxicon Twig function is marked issafe='html', so Twig never escapes its output. Icon::toHtml inlines the SVG source verbatim into the page. Browsers execute elements and on event-handler attributes found inside inline SVG, making any unsanitized icon a vector for cross-site...

Dot-only cookie domains match all hosts

Impact CookieJar incorrectly accepts cookies with a dot-only Domain attribute, such as Domain=., Domain=.., Domain=..., and whitespace-padded variants such as Domain= . . In affected versions, SetCookie::matchesDomain removes leading dots from the cookie domain, normalizing dot-only values to the...

Silent HTTPS proxy downgrade to cleartext

Impact The built-in cURL handlers GuzzleHttp\Handler\CurlHandler and GuzzleHttp\Handler\CurlMultiHandler, used by default whenever the PHP cURL extension is available accept an https:// proxy — a proxy reached over a TLS-encrypted connection — through the proxy request option, client-level proxy...

CRLF injection in HTTP start-line serialization

Impact guzzlehttp/psr7 did not reject CR/LF characters in certain first-party HTTP start-line fields: the request method, protocol version, and response reason phrase. If an application placed attacker-controlled data into one of those fields and later serialized the PSR-7 message as raw HTTP/1.x...

RSA1_5 (RSAES-PKCS1-v1_5) decryption lacks implicit rejection, exposing a Bleichenbacher/Marvin padding oracle

Impact RSACrypt::decryptWithRSA15 used by the RSA15 key-encryption algorithm implements RSAES-PKCS1-v15 decryption by inspecting the padding after RSADP and throwing InvalidArgumentException as soon as the padding is malformed. It does not implement the implicit-rejection countermeasure required ...

Chacha20Poly1305 key-encryption algorithm discards the Poly1305 authentication tag, performing no authentication on decryption

Impact The experimental Chacha20Poly1305 key-encryption algorithm generates the 16-byte Poly1305 authentication tag during encryptKey but discards it: the tag is never written to the header and therefore never reaches the wire. On the receiving side, decryptKey calls...
