Ai-bolit: Improper Neutralization of Directives in Dynamically Evaluated Code

CVE-2025-65530 is a high-severity improper neutralization of directives in dynamically evaluated code vulnerability in Ai-bolit from Cloudlinux, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 32.7.4-1 as the first without the flaw, so updating Ai-bolit to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.32% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Ai-bolit to 32.7.4-1 or a later version.
  2. Read the advisory on blog.imunify360.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  4. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

An eval injection in the malware de-obfuscation routines of CloudLinux ai-bolit before v32.7.4 allows attackers to overwrite arbitrary files as root via scanning a crafted file.

The underlying weakness: Improper Neutralization of Directives in Dynamically Evaluated Code

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. eval).

How developers prevent this class of flaw

  • If possible, refactor your code so that it does not need to use eval() at all.
  • For Python programs, it is frequently encouraged to use the ast.literal_eval() function instead of eval, since it is intentionally designed to avoid executing code. However, an adversary could still cause excessive memory or stack consumption via deeply nested structures, so the python documentation discourages use of ast.literal_eval() on untrusted data.
