Pebbletemplates: >> Pebble Templates >> 3.1.2 Security Vulnerabilities
Versions of the package io.pebbletemplates:pebble from 0 and before 4.1.0 are vulnerable to External Control of File Name or Path via the include tag. A high privileged attacker can access sensitive local files by crafting malicious notification templates that leverage this tag to include files like /etc/passwd or /proc/1/environ.
Workaround
This vulnerability can be mitigated by disabling the include macro in Pebble Templates:
java
new PebbleEngine.Builder()
.registerExtensionCustomizer(new DisallowExtensionCustomizerBuilder()
.disallowedTokenParserTags(List.of("include"))
.build())
.build();
