CVE-2026-10532NVD
Description
Deserialization of untrusted data vulnerability in QOS.CH Sarl logback logback-core (HardenedObjectInputStream (logback-core) modules) allows Object Injection, albeit heavily restricted.
More precisely, an attacker able to influence serialized data sent to
SimpleSocketServer or SimpleSSLSocketServer can instantiate Proxy objects.
Although deserialization is heavily restricted by HardenedObjectInputStream and no
practical way to achieve remote code execution or significant privilege
escalation has been identified, this issue constitutes a bypass of the
intended security restrictions.
This issue affects logback: through 1.5.33 inclusive.
