## Key facts

- **Exploitation phase:** Limited Exploitation. The vulnerability is known but shows very limited attacker interest or exploitation activity.
- **CVSS score:** 6.1
- **Public exploit available:** Yes
- **Affected products:** UseMemos Memos
- **Weaknesses:** CWE-918 (Server-Side Request Forgery (SSRF)); CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'))
- **Tags:** web_application

## Description

Memos is a privacy-first, lightweight note-taking service. In Memos 0.13.2, an SSRF vulnerability exists at the /o/get/image that allows unauthenticated users to enumerate the internal network and retrieve images. The response from the image request is then copied into the response of the current server request, causing a reflected XSS vulnerability. Version 0.22.0 of memos removes the vulnerable file.

## CrowdSec analysis

[CVE-2024-29029](https://euvd.enisa.europa.eu/vulnerability/CVE-2024-29029) is a vulnerability in Memos 0.13.2 that allows unauthenticated users to exploit a server-side request forgery (SSRF) flaw at the /o/get/image endpoint, enabling internal network enumeration and image retrieval. Additionally, the vulnerability leads to a reflected cross-site scripting (XSS) issue, potentially allowing attackers to execute malicious scripts in users' browsers. This combination of SSRF and XSS could be leveraged for further attacks such as data theft or network reconnaissance.

CrowdSec has been tracking this vulnerability and its exploits since 24th of September 2025.

Data from the CrowdSec community indicates that exploitation of CVE-2024-29029 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.
In addition, according to the CrowdSec network, attack volume against CVE-2024-29029 has dipped slightly compared to the previous week. Although still commonly targeted, the decline suggests a cooling-off period. Long-term relevance remains, but attention is waning.

Attackers exploit the `/o/get/image` endpoint by supplying a remote URL to the `url` parameter, enabling SSRF and reflected XSS attacks. These requests often include external image URLs and result in the server reflecting attacker-controlled content in the response.
