## Key facts

- **Exploitation phase:** Limited Exploitation. The vulnerability is known but shows very limited attacker interest or exploitation activity.
- **CVSS score:** 5.3
- **Public exploit available:** Yes
- **Affected products:** Imgproxy
- **Weaknesses:** CWE-918 (Server-Side Request Forgery (SSRF))
- **Tags:** web_application

## Description

Imgproxy is server for resizing, processing, and converting images. Imgproxy does not block the 0.0.0.0 address, even with IMGPROXY_ALLOW_LOOPBACK_SOURCE_ADDRESSES set to false. This can expose services on the local host. This vulnerability is fixed in 3.27.2.

## CrowdSec analysis

[CVE-2025-24354](https://euvd.enisa.europa.eu/vulnerability/CVE-2025-24354) is a vulnerability in imgproxy that allows remote attackers to access services on the local host by exploiting improper blocking of the 0.0.0.0 address, even when loopback source addresses are meant to be restricted. This flaw could be leveraged for unauthorized information disclosure or internal network probing until patched in version 3.27.2.

CrowdSec has been tracking this vulnerability and its exploits since 26th of November 2025.

Data from the CrowdSec community indicates that exploitation of CVE-2025-24354 is highly selective and intelligence-driven. Threat actors use advanced reconnaissance and carefully choose their targets, often as part of sophisticated campaigns or advanced persistent threat operations.
Data from the CrowdSec community also indicates a gradual decrease in attacks targeting CVE-2025-24354. While still present in the wild, exploitation levels have dropped noticeably week-over-week. This may signal that the vulnerability is becoming less relevant or that defenses are improving fast enough for attackers to lose interest.

Attackers exploit this vulnerability by sending requests to endpoints like `/unsafe/plain/` with URLs pointing to internal or arbitrary hosts, attempting to force imgproxy to fetch resources from addresses such as `0.0.0.0` or attacker-controlled domains, leading to potential SSRF and exposure of internal services.
