Hi, The following vulnerability was published for logback. CVE-2026-9828[0]: | 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 objects | from classes in the java.lang and java.util packages that are not | explicitly blocked. 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 1.5.32 | inclusive. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
