CVE-2025-53833 is a critical-severity (CVSS 10) CWE-1336 vulnerability in binarytorch/larecipe. A fix is available for binarytorch/larecipe — see the affected versions and patch details below.
LaRecipe is vulnerable to Server-Side Template Injection attacks
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Real-World Exposure
binarytorch/larecipeReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Attackers could:
- Execute arbitrary commands on the server
- Access sensitive environment variables
- Escalate access depending on server configuration
A critical vulnerability was discovered in LaRecipe that allows an attacker to perform Server-Side Template Injection (SSTI), potentially leading to Remote Code Execution (RCE) in vulnerable configurations.
Patches
Users are strongly advised to upgrade to version v2.8.1 or later.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for binarytorch/larecipe, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update binarytorch/larecipe to 2.8.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-53833 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
