Short explanation
The CVE-2026-44265 vulnerability in Elo allows arbitrary code execution in JavaScript, Ruby, and Python targets and SQL injection in SQL targets due to unvalidated programmatic AST fields.
This security flaw enables attackers to turn unvalidated inputs into executable expressions, creating the risk of executing arbitrary code or manipulating databases on affected systems.
What should be done?
- Update Elo to version 1.0.1 or later
- Follow vendor advisory guidelines
Chain of evidence and sources
Elo, 1.0.1 öncesi sürümlerde programatik AST alanlarını doğrulamadan işlemektedir.
Zafiyet, JavaScript, Ruby ve Python hedeflerinde rastgele kod yürütmeye ve SQL hedeflerinde SQL enjeksiyonuna neden olur.
Show the technical text from the sources
Elo is a purely functional expression language for no-code tools. Prior to 1.0.1, Elo's programmatic AST API accepts arbitrary values from JSON-deserialized input, plugin output, or other untyped sources and interpolates them into generated JavaScript, Ruby, Python, or SQL without runtime syntax validation. The affected fields are int_literal / float_literal .value, variable.name, member_access.property, object_literal keys, datapath segments, lambda.params[].name, and the SQL let binding name. Crafted values become executable expressions or identifiers, allowing arbitrary code execution in JavaScript, Ruby, and Python targets and SQL injection in the SQL target. This programmatic AST-object path is distinct from the plain-string constructor-chain sandbox escape. This issue is fixed in version 1.0.1.
