GHSA-jjx5-fq5g-8xpc
Symfony Cryptographic Vulnerability The nextBytes function in the SecureRandom class in Symfony before 2.3.37, 2.6.x before 2.6.13, and 2.7.x before 2.7.9 does not properly generate random numbers when used with PHP 5.x without the paragonie/random_compat library and the openssl_random_pseudo_bytes function fails, which makes it easier for attackers to defeat cryptographic protection mechanisms via unspecified vectors.

Symfony Denial of Service Via Long Password Hashing The Security component in Symfony 2.0.x before 2.0.25, 2.1.x before 2.1.13, 2.2.x before 2.2.9, and 2.3.x before 2.3.6 allows remote attackers to cause a denial of service (CPU consumption) via a long password that triggers an expensive hash computation, as demonstrated by a PBKDF2 computation, a similar issue to CVE-2013-5750.

Symfony Session Fixation Vulnerability A session fixation vulnerability within the "Remember Me" login feature allows an attacker to impersonate the victim towards the web application if the session id value was previously known to the attacker. This issue has been fixed in Symfony 2.3.35, 2.6.12, and 2.7.7. Note that no fixes are provided for Symfony 2.4 and 2.5 as they are not maintained anymore. Symfony 2.8 and 3.0 haven't been released yet and the fix will be included in their first stable releases.

Symfony Host Header Injection vulnerability in the HttpFoundation component Symfony 2.0.X before 2.0.24, 2.1.X before 2.1.12, 2.2.X before 2.2.5, and 2.3.X before 2.3.3 have an issue in the HttpFoundation component. The Host header can be manipulated by an attacker when the framework is generating an absolute URL. A remote attacker could exploit this vulnerability to inject malicious content into the Web application page and conduct various attacks.

Symfony Vulnerable to Timing Attack Symfony 2.3.x before 2.3.35, 2.6.x before 2.6.12, and 2.7.x before 2.7.7 might allow remote attackers to have unspecified impact via a timing attack involving the (1) `Symfony/Component/Security/Http/RememberMe/PersistentTokenBasedRememberMeServices` or (2) `Symfony/Component/Security/Http/Firewall/DigestAuthenticationListener` class in the Symfony Security Component, or (3) legacy CSRF implementation from the `Symfony/Component/Form/Extension/Csrf/CsrfProvider/DefaultCsrfProvider` class in the Symfony Form component.

GHSA-q8j7-fjh7-25v5
Symfony collectionCascaded and collectionCascadedDeeply fields security bypass When using the Validator component, if `Symfony\\Component\\Validator\\Mapping\\Cache\\ApcCache` is enabled (or any other cache implementing `Symfony\\Component\\Validator\\Mapping\\Cache\\CacheInterface`), some information is lost during serialization (the `collectionCascaded` and the `collectionCascadedDeeply` fields). As a consequence, arrays or traversable objects stored in fields using the `@Valid` constraint are not traversed by the validator as soon as the validator configuration is loaded from the cache.
