Symfony UX is a JavaScript ecosystem for Symfony. From 2.2.0 until 2.36.0 and 3.1.0, Symfony\UX\Autocomplete\Doctrine\EntitySearchUtil::addSearchClause() builds the LIKE expression used by the autocomplete endpoint by wrapping the client-supplied query in %...% without escaping SQL LIKE wildcards (%, _, \), allowing unauthenticated users to turn the public BaseEntityAutocompleteType endpoint into …

Symfony UX is a JavaScript ecosystem for Symfony. From 2.8.0 until 2.36.0 and 3.1.0, the HMAC computed by Symfony\UX\LiveComponent\LiveComponentHydrator covered only sorted prop key/value pairs and did not include the component name, the slot identifier (props vs propsFromParent), or request context, allowing a signed blob minted for one component or slot to be replayed in another and set a read-o…

Twig is a template language for PHP. Prior to 3.27.0, the per-template filter, tag, and function allow-list verdict is computed when a Template instance is constructed and can remain cached after sandbox state changes between renders, allowing a later sandboxed render to reuse a template that was originally checked with a different or empty policy. This issue is fixed in version 3.27.0.

Twig is a template language for PHP. Prior to 3.27.0, the column filter passes the active sandbox state as a boolean but does not forward the current Source to SandboxExtension::checkPropertyAllowed(), so SourcePolicyInterface decisions are lost and a template author can read public or magic properties not allowed by the sandbox policy. This issue is fixed in version 3.27.0.

Twig is a template language for PHP. Prior to 3.26.0, {% sandbox %}{% include %} can include a template that was previously loaded outside the sandbox without re-invoking checkSecurity(), allowing the cached template to use tags, filters, and functions that should have been denied by SecurityPolicy::checkSecurity(). This issue is fixed in version 3.26.0.

Twig is a template language for PHP. From 3.15.0 until 3.26.0, _self.() and import-alias dynamic attribute syntax can concatenate an attacker-controlled string into a MacroReferenceExpression name without identifier validation, causing raw PHP to be emitted into the generated template source and executed at template-load time. This issue is fixed in version 3.26.0.

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.52, 6.4.40, 7.4.12, and 8.0.12, Symfony\Component\Yaml\Parser resolved YAML collection aliases recursively, allowing a small untrusted YAML input to expand into a multi-gigabyte structure and exhaust memory.
