Memos 0.22 is vulnerable to Stored Cross site scripting (XSS) vulnerabilities by the upload attachment and user avatar features. Memos does not verify the content type of the uploaded data and serve it back as is. An authenticated attacker can use this to elevate their privileges when the stored XSS is viewed by an admin.
When Memos 0.22 is configured to store objects locally, an attacker can create a file via the CreateResource endpoint containing a path traversal sequence in the name, allowing arbitrary file write on the server.
The Memos application, up to version v0.24.3, allows for the embedding of markdown images with arbitrary URLs. When a user views a memo containing such an image, their browser automatically fetches the image URL without explicit user consent or interaction beyond viewing the memo. This can be exploited by an attacker to disclose the viewing user's IP address, browser User-Agent string, and potentially other request-specific information to the attacker-controlled server, …
elestio memos v0.23.0 is vulnerable to Server-Side Request Forgery (SSRF) due to insufficient validation of user-supplied URLs, which can be exploited to perform SSRF attacks.
A stored cross-site scripting (XSS) vulnerability was discovered in usememos/memos version 0.9.1. This vulnerability allows an attacker to upload a JavaScript file containing a malicious script and reference it in an HTML file. When the HTML file is accessed, the malicious script is executed. This can lead to the theft of sensitive information, such as login credentials, from users visiting the affected website. The issue has been fixed in version …
memos is a privacy-first, lightweight note-taking service. A CORS misconfiguration exists in memos 0.20.1 and earlier where an arbitrary origin is reflected with Access-Control-Allow-Credentials set to true. This may allow an attacking website to make a cross-origin request, allowing the attacker to read private information or make privileged changes to the system as the vulnerable user account.
memos is a privacy-first, lightweight note-taking service. In memos 0.13.2, an SSRF vulnerability exists at the /o/get/httpmeta that allows unauthenticated users to enumerate the internal network and receive limited html values in json form. This vulnerability is fixed in 0.16.1.
memos is a privacy-first, lightweight note-taking service. In memos 0.13.2, an SSRF vulnerability exists at the /api/resource that allows authenticated users to enumerate the internal network. Version 0.22.0 of memos removes the vulnerable file.
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.
