dynaconf: jinja2: Dynaconf: Arbitrary code execution via Server-Side Template Injection

A flaw was found in dynaconf, a Python configuration management tool. This Server-Side Template Injection SSTI vulnerability occurs due to unsafe template evaluation in the @Jinja resolver when the jinja2 package is installed. A remote attacker could exploit this by embedding malicious template...

automation-controller: automation-controller-container: automation-controller: Notification template Jinja whitelist bypass via conditional gating leaks tracebacks

Notification template Jinja AST whitelist only inspects static Getattr nodes. Dynamic subscripts job'job'+'env' and % if job.id 100 % conditional gating bypass both the AST check and the test-render stub has small job.id. At runtime, the gated branch executes and exceptions write full tracebacks...

automation-controller: automation-controller: incomplete sanitize_jinja() regex allows Jinja template injection into ad-hoc module_args, Machine-credential fields, and Host names, reaching ansible-core templating in the execution environment

A flaw was found in the automation-controller input-validation guard sanitizejinja. The function uses two regular expressions to reject user-supplied Jinja, but the patterns stop at the first interior '' or '%' character, so a Jinja expression containing an inner brace for example an empty dict i...
