Insecure Deserialization

Remote code execution is possible in DataDog's dd-trace-java agent versions prior to 1.60.3 when running on JDK 16 or earlier with exposed JMX/RMI ports. The vulnerability stems from unsafe deserialization in the RMI instrumentation's custom endpoint, allowing network-accessible attackers to execute arbitrary code if gadget-chain libraries exist on the classpath. Vendor-released patch: version 1.60.3. No public exploit identified at time of analysis, though the issue was responsibly disclosed through DataDog's bug bounty program by Mohamed Amine ait Ouchebou.

The Frontend Admin by DynamiApps plugin for WordPress contains a PHP Object Injection vulnerability affecting all versions up to and including 3.28.31. Authenticated attackers with Editor-level privileges or higher can exploit unsafe deserialization of the 'post_content' field in admin_form posts to inject malicious PHP objects and achieve remote code execution through available POP chains. This represents a critical risk for WordPress sites using this plugin with elevated user accounts.

Saloon PHP library versions prior to 4.0.0 contain a PHP object injection vulnerability in the AccessTokenAuthenticator::unserialize() method, which unsafely deserializes OAuth token state using unserialize() with allowed_classes set to true.
