# Security digest: April 4, 2025

1 known exploited (cisa kev) addition and 1 critical advisory.

## Take stock

- Do you run any of these? Ivanti Connect Secure, Policy Secure, and ZTA Gateways. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2025-04-11.
- PyPI: 1 critical advisory ( bentoml ). Check with pip-audit (or: pip show <package>) .
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Known exploited (CISA KEV)

- [CVE-2025-22457](https://erroneo.us/security/cve/CVE-2025-22457/index.md) Ivanti Connect Secure, Policy Secure, and ZTA Gateways: Ivanti Connect Secure, Policy Secure, and ZTA Gateways Stack-Based Buffer Overflow Vulnerability (CISA due 2025-04-11)

## Critical advisories

- [CVE-2025-27520](https://erroneo.us/security/cve/CVE-2025-27520/index.md) BentoML Allows Remote Code Execution (RCE) via Insecure Deserialization — PyPI bentoml >= 1.3.4, < 1.4.3 → 1.4.3
