Title
JinJava Bypass through ForTag leads to Arbitrary Java Execution
Summary
JinJava is a Java-based template engine based on django template syntax, adapted to render jinja templates. Prior to versions 2.7.6 and 2.8.3, JinJava is vulnerable to arbitrary Java execution via bypass through ForTag. This allows arbitrary Java class instantiation and file access bypassing built-in sandbox restrictions. This issue has been patched in versions 2.7.6 and 2.8.3.

CVE-2025-59340 (GCVE-0-2025-59340)

Vulnerability from nvd – Published: 2025-09-17 20:01 – Updated: 2025-09-18 15:45

Title
jinjava Sandbox Bypass via JavaType-Based Deserialization
Summary
jinjava is a Java-based template engine based on django template syntax, adapted to render jinja templates. Priori to 2.8.1, by using mapper.getTypeFactory().constructFromCanonical(), it is possible to instruct the underlying ObjectMapper to deserialize attacker-controlled input into arbitrary classes. This enables the creation of semi-arbitrary class instances without directly invoking restricted methods or class literals. As a result, an attacker can escape the sandbox and instantiate classes such as java.net.URL, opening up the ability to access local files and URLs(e.g., file:///etc/passwd). With further chaining, this primitive can potentially lead to remote code execution (RCE). This vulnerability is fixed in 2.8.1.

CVE-2026-25526 (GCVE-0-2026-25526)

Vulnerability from cvelistv5 – Published: 2026-02-04 21:26 – Updated: 2026-02-05 21:01

Title
JinJava Bypass through ForTag leads to Arbitrary Java Execution
Summary
JinJava is a Java-based template engine based on django template syntax, adapted to render jinja templates. Prior to versions 2.7.6 and 2.8.3, JinJava is vulnerable to arbitrary Java execution via bypass through ForTag. This allows arbitrary Java class instantiation and file access bypassing built-in sandbox restrictions. This issue has been patched in versions 2.7.6 and 2.8.3.
Severity ?

CVE-2025-59340 (GCVE-0-2025-59340)

Vulnerability from cvelistv5 – Published: 2025-09-17 20:01 – Updated: 2025-09-18 15:45
VLAI?
Title
jinjava Sandbox Bypass via JavaType-Based Deserialization
Summary
jinjava is a Java-based template engine based on django template syntax, adapted to render jinja templates. Priori to 2.8.1, by using mapper.getTypeFactory().constructFromCanonical(), it is possible to instruct the underlying ObjectMapper to deserialize attacker-controlled input into arbitrary classes. This enables the creation of semi-arbitrary class instances without directly invoking restricted methods or class literals. As a result, an attacker can escape the sandbox and instantiate classes such as java.net.URL, opening up the ability to access local files and URLs(e.g., file:///etc/passwd). With further chaining, this primitive can potentially lead to remote code execution (RCE). This vulnerability is fixed in 2.8.1.
Severity ?
