CVE-2025-53833: LaRecipe is vulnerable to Server-Side Template Injection attacks

Should you act?

High exploit likelihood

EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
• EPSS 9.1%, percentile 95: FIRST’s model estimates a 9.1% chance of exploitation activity in the next 30 days, higher than 95% of all scored CVEs (very high). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Only applies if your dependency tree includes binarytorch/larecipe (Composer (PHP)) < 2.8.1, fixed in 2.8.1. Check your lockfile, including transitive dependencies.

What it is

LaRecipe is an application that allows users to create documentation with Markdown inside a Laravel app. Versions prior to 2.8.1 are vulnerable to Server-Side Template Injection (SSTI), which could potentially lead to Remote Code Execution (RCE) in vulnerable configurations. Attackers could execute arbitrary commands on the server, access sensitive environment variables, and/or escalate access depending on server configuration. Users are strongly advised to upgrade to version v2.8.1 or later to receive a patch.

From the GitHub advisory

Impact Attackers could: 1. Execute arbitrary commands on the server 2. Access sensitive environment variables 3. 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.
