0.21.0- Upgrade github.com/usememos/memos to this version or later
Description
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.
Affected versions
Go
| Package | Vulnerable | Fixed in |
|---|---|---|
| github.com/usememos/memos | < 0.21.0 |
0.21.0 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
github.com/usememos/memos Go → 0.21.0

go get github.com/usememos/memos@v0.21.0 && go mod tidy

Weakness
CWE-942: Permissive Cross-domain Security Policy with Untrusted Domains
The product uses a web-client protection mechanism such as a Content Security Policy (CSP) or cross-domain policy file, but the policy includes untrusted domains with which the web client is allowed to communicate.
How to prevent it
- Architecture and Design, Operation: Define a restrictive Content Security Policy [REF-1486] or cross-domain policy file.
- Architecture and Design, Operation: Avoid using wildcards in the CSP / cross-domain policy file. Any domain matching the wildcard expression will be implicitly trusted, and can perform two-way interaction with the target server.
- Architecture and Design, Operation: For Flash, modify crossdomain.xml to use meta-policy options such as 'master-only' or 'none' to reduce the possibility of an attacker planting extraneous cross-domain policy files on a server.
