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.
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 ?
9.8 (Critical)
