A serialization vulnerability in logback receiver component part of logback allows an attacker to mount a Denial-Of-Service attack by sending poisoned data.

This is only exploitable if logback receiver component is deployed. See https://logback.qos.ch/manual/receivers.html

QOS.CH logback-core Expression Language Injection vulnerability

CVE-2024-12798 / GHSA-pr98-23f8-jwxv

More information

Details

ACE vulnerability in JaninoEventEvaluator by QOS.CH logback-core up to and including version 1.5.12 in Java applications allows attackers to execute arbitrary code by compromising an existing logback configuration file or by injecting an environment variable before program execution.

Malicious logback configuration files can allow the attacker to execute arbitrary code using the JaninoEventEvaluator extension.

A successful attack requires the user to have write access to a configuration file. Alternatively, the attacker could inject a malicious environment variable pointing to a malicious configuration file. In both cases, the attack requires existing privilege.

QOS.CH logback-core Server-Side Request Forgery vulnerability

CVE-2024-12801 / GHSA-6v67-2wr5-gvf4

More information

Details

Server-Side Request Forgery (SSRF) in SaxEventRecorder by QOS.CH logback version 1.5.12 on the Java platform, allows an attacker to forge requests by compromising logback configuration files in XML.

The attacks involves the modification of DOCTYPE declaration in  XML configuration files.

QOS.CH logback-core is vulnerable to Arbitrary Code Execution through file processing

CVE-2025-11226 / GHSA-25qh-j22f-pwp8

More information

Details

QOS.CH logback-core versions up to 1.5.18 contain an ACE vulnerability in conditional configuration file processing in Java applications. This vulnerability allows an attacker to execute arbitrary code by compromising an existing logback configuration file or by injecting a malicious environment variable before program execution.

A successful attack requires the Janino library and Spring Framework to be present on the user's class path. Additionally, the attacker must have write access to a configuration file. Alternatively, the attacker could inject a malicious environment variable pointing to a malicious configuration file. In both cases, the attack requires existing privileges.

Logback allows an attacker to instantiate classes already present on the class path

CVE-2026-1225 / GHSA-qqpg-mvqg-649v

More information

Details

ACE vulnerability in configuration file processing by QOS.CH logback-core up to and including version 1.5.24 in Java applications, allows an attacker to instantiate classes already present on the class path by compromising an existing logback configuration file.

The instantiation of a potentially malicious Java class requires that said class is present on the user's class-path. In addition, the attacker must have write access to a configuration file. However, after successful instantiation, the instance is very likely to be discarded with no further ado.

QOS.CH Sarl logback logback-core has a deserialization of untrusted data vulnerability

CVE-2026-9828 / GHSA-p47f-322f-whfh

More information

Details

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.

Severity

• CVSS Score: 1.2 / 10 (Low)
• Vector String: CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N/E:P/RE:L/U:Green

Logback vulnerable to Object Injection through HardenedObjectInputStream modules

CVE-2026-10532 / GHSA-jhq6-gfmj-v8fx

More information

Details

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.
