deserialization
About this tag
Deserialization vulnerabilities are a recurring security concern across diverse software ecosystems, as demonstrated by recent CVEs discussed on WindowsForum. These flaws occur when untrusted data is deserialized without proper validation, potentially leading to remote code execution, memory corruption, or denial of service. Examples include CVE-2021-38190 in the Rust nalgebra crate, CVE-2023-41330 in PHP's Knp Snappy library, CVE-2024-2494 in libvirt's RPC deserialization, CVE-2025-68664 in LangChain Core, CVE-2025-10492 in Hitachi Asset Suite, CVE-2024-9005 in Schneider Electric's Power Monitoring Expert, CVE-2025-62204 in Microsoft SharePoint, and CVE-2025-59287 in Windows Server Update Services. These cases highlight the importance of patching deserialization bugs promptly to prevent exploitation.
