How the CVE Works
LaRecipe versions before 2.8.1 fail to properly sanitize user-supplied input in template rendering, allowing attackers to inject malicious template code. The engine processes unfiltered payloads, enabling Server-Side Template Injection (SSTI). Attackers can craft payloads to execute arbitrary system commands, leading to Remote Code Execution (RCE). The vulnerability arises due to unsafe dynamic template compilation without proper sandboxing.
DailyCVE Form

Version: < 2.8.1
Vulnerability: SSTI → RCE
Severity: Critical
Date: Jul 14, 2025
Prediction: Patch expected by Jul 20, 2025
What Undercode Say
curl -X POST http://target/larecipe -d "payload={{malicious_code}}"
exploit = "{{77}}"
response = requests.post(vuln_endpoint, data={"input": exploit})
How Exploit
- Craft SSTI payload (e.g.,
{{system('id')}}) - Inject via vulnerable input field
- Gain RCE on server
Protection from this CVE
- Upgrade to v2.8.1+
- Disable dynamic template rendering
- Sanitize user inputs
Impact
