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

### Impact `RSACrypt::decryptWithRSA15()` (used by the `RSA1_5` key-encryption algorithm) implements RSAES-PKCS1-v1_5 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 by RFC 3447 §7.2.2 / RFC 8017 §7.1.2 (return a deterministic pseudo-random value of the expected length on padding failure and let the downstream step fail uniformly). From a JWE caller this yields a Bleichenbacher/Marvin padding oracle: an attacker submitting adaptively crafted `encrypted_key` values can distinguish (a) padding

PHP JWT Framework: JWSVerifier uses algorithm from unprotected header, enabling algorithm confusion attacks

## Summary `JWSVerifier::getAlgorithm()` in `src/Library/Signature/JWSVerifier.php` (line 144) merges protected and unprotected headers using PHP's spread operator: ```php $completeHeader = [...$signature->getProtectedHeader(), ...$signature->getHeader()]; ``` In PHP, when spreading arrays with duplicate string keys, the **last array's values take precedence**. Since the unprotected header (`getHeader()`) is spread second, an attacker can override the integrity-protected `alg` parameter by placing a different value in the unprotected header. This creates a Time-of-Check/Time-of-Use (TOCTOU) vulnerability: 1. `HeaderCheckerManager` validat

PHP JWT Library: PBES2-HS*+A*KW unwrap accepts an unbounded p2c iteration count, enabling CPU-amplification denial of service

### Impact When a JWE uses a password-based key-encryption algorithm (`PBES2-HS256+A128KW`, `PBES2-HS384+A192KW`, `PBES2-HS512+A256KW`), `PBES2AESKW::unwrapKey()` reads the `p2c` (PBKDF2 iteration count) parameter directly from the attacker-controlled JOSE header and passes it to `hash_pbkdf2()` with **no upper bound**. The only validation performed (`checkHeaderAdditionalParameters()`) was `is_int($p2c) && $p2c > 0`. An unauthenticated attacker can craft a single JWE whose protected header sets a very large `p2c` (e.g. `100_000_000` ≈ 87 s of CPU, or `PHP_INT_MAX`), forcing a worker to spend an arbitrary amount of CPU inside PBKDF2 **befor

PHP JWT Framework: 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 `openssl_decrypt('chacha20-poly1305', ...)` **without the tag argument**, which makes OpenSSL skip authentication entirely. As a result the AEAD construction is silently degraded to unauthenticated ChaCha20: a tampered encrypted CEK is accepted, and because ChaCha20 is a stream cipher, a single-byte change in the ciphertext propagates as a single-byte change i

spomky-labs/otphp: Mass-assignment in Factory::loadFromProvisioningUri lets a hostile provisioning URI corrupt OTP state or leak an uncaught TypeError

## Summary `OTPHP\Factory::loadFromProvisioningUri()` parses an attacker-supplied `otpauth://` URI and forwards **every** query key to `OTP::setParameter($key, $value)`. `setParameter()` resolves the name with `property_exists($this, $parameter)` and performs a dynamic write `$this->{$parameter} = $value` (`src/OTP.php:196-197`). Because the query keys are entirely controlled by whoever produced the URI, a URI can target the internal properties of the OTP object that are not meant to be set from a URI: `parameters`, `issuer`, `label`, `issuer_included_as_parameter`, and (on TOTP) the readonly `clock`. This is an instance of object property m

spomky-labs/otphp: Unbounded digits parameter in a provisioning URI triggers an uncaught DivisionByZeroError in OTP generation

## Summary The `digits` parameter parsed from a provisioning URI is validated only with a lower bound (`$value > 0`) and has no upper bound (`src/OTP.php:353-357`). OTP generation computes `$code % (10 ** $this->getDigits())` (`src/OTP.php:283`). When `digits` is large enough that `10 ** digits` overflows PHP's integer range and the `(int)` cast yields `0` (around `digits >= 40` on 64-bit PHP 8.x), the modulo operand becomes `0` and PHP raises a `DivisionByZeroError`. ## Impact `OTPHP\Factory::loadFromProvisioningUri()` forwards the attacker-controlled `digits` query value to `setParameter('digits', $value)`, so a hostile URI such as `otpa

Cotonti stored XSS via PFS folder title

Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to stored Cross-Site Scripting in the Personal File Storage (PFS) module. A folder title (pff_title) is imported with the 'TXT' filter, which does not strip or encode HTML (the tag check in cot_import is disabled), so an authenticated user can store HTML/JavaScript in a folder title.

Cotonti CSRF in PFS folder edit allows unauthorized folder modification

Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to Cross-Site Request Forgery in the Personal File Storage (PFS) module. In modules/pfs/inc/pfs.editfolder.php, the folder update action ('a=update') updates folder metadata (title, description, public/gallery flags) without calling cot_check_xg to validate the anti-CSRF token.

Cotonti CSRF in PFS allows forced arbitrary file upload

Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to Cross-Site Request Forgery in the Personal File Storage (PFS) module. In modules/pfs/inc/pfs.main.php, the file upload action ('a=upload') processes uploaded files without calling cot_check_xg to validate the anti-CSRF token, even though sibling actions such as 'delete' (line 272) do.

Cotonti CSRF in admin.rights.php allows privilege escalation

Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to Cross-Site Request Forgery in the administration rights handler. In system/admin/admin.rights.php, the rights update action ('a=update') modifies group access rights (including via cot_auth_add_group) without calling cot_check_xg to validate the anti-CSRF token.

CakePHP: View::element() is missing a path containment check

CakePHP is a rapid development framework for PHP. In versions 4.5.11 and earlier, 4.6.0 through 4.6.3, 5.0.0 through 5.1.6, 5.2.0 through 5.2.12, and 5.3.0 through 5.3.5, View::_getElementFileName() does not check that the resolved element path is within the application/plugin view template paths. When element names are created with specifically crafted user-supplied data this weakness can be leveraged to include other PHP files on the server. Patched releases are available in 5.3.6, 5.2.13, 5.1.7, 4.6.4, and 4.5.11.

PHP Standard Library: HTTP/2 server-side missing content-length validation enables request smuggling

PHP Standard Library (PSL) is set of APIs covering async, collections, networking, I/O, cryptography, terminal UI, etc. In versions 6.1.0, 6.1.1 and 6.2.0, the Psl\H2\ServerConnection does not validate that the total bytes received in DATA frames match the content-length header declared in the HEADERS frame, allowing request smuggling. This is in violation of RFC 9113 §8.1.1. A malicious client is able to send more DATA bytes than declared, smuggling additional content past application-level size limits and send fewer DATA bytes than declared and close the stream early, causing applications that trust the declared length to behave incorrectly

Pimcore CMS 12.3.8 Twig Sandbox Bypass via SecurityPolicy checkMethodAllowed

Pimcore CMS/DXP version 12.3.8 contains a sandbox bypass vulnerability that allows authenticated administrative attackers to execute arbitrary methods on PHP objects by exploiting empty checkMethodAllowed() and checkPropertyAllowed() implementations in the custom Twig SecurityPolicy. Attackers can supply malicious Twig templates through the DataObject ClassDefinition Layout\Text component to perform arbitrary file reads, execute arbitrary database queries, and potentially achieve remote code execution via PHP object gadget chains, with the pimcore_* function wildcard further broadening the bypass to all Pimcore Twig functions.

Laravel Framework: Temporary Signed URL Path Confusion

A vulnerability in Laravel's local filesystem driver allows temporary signed URLs to be parsed ambiguously, potentially misrouting requests and bypassing expiration enforcement. Under certain conditions, a generated temporary signed URL can be interpreted differently by the server than intended at signing time. This may cause requests to resolve to an unintended resource, and can prevent expiration from being enforced, allowing expired URLs to remain valid indefinitely. ### Impact - Expired temporary URLs may continue to be accepted - Requests may resolve to a different resource than the one that was signed - The upload variant may allow wr

Slim has Reflected XSS in the HtmlErrorRenderer

Slim is a PHP micro framework that enables users to write simple web applications and APIs. In versions 4.4.0 through 4.15, if an application uses HttpException::setTitle() and/or setDescription() to include untrusted/request-derived data in the error title or description (e.g. "No products found matching '{$query}'."), an attacker could inject arbitrary HTML/JavaScript that executes in the victim's browser when they encounter an HTML error page generated by Slim. The vulnerability is present even with displayErrorDetails = false as the unescaped title and description are rendered on this error path. Built-in exceptions (HttpNotFoundException
