CVE-2023-43091
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA flaw was found in GNOME Maps, which is vulnerable to a code injection attack via its service.json configuration file. If the configuration file is malicious, it may execute arbitrary code.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisUntrusted input is placed into a web page without being neutralised, so an attacker's markup or script executes in another user's browser. That can hijack sessions, capture keystrokes, or silently perform actions as the victim. Fixing it properly means context-aware output encoding everywhere data meets HTML, backed by a content-security policy as a second line of defence.

gnome-maps 43.7 or later (for 43.x branch); gnome-maps 44.4 or later (for 44.x branch)
- 1. Check the currently installed version of gnome-maps (e.g., via your package manager or 'gnome-maps --version')
- 2. If running version 43.0-43.6, upgrade to gnome-maps version 43.7 or later
- 3. If running version 44.0-44.3, upgrade to gnome-maps version 44.4 or later
- 4. For distributions using package managers, run: apt update && apt upgrade gnome-maps (Debian/Ubuntu) or dnf update gnome-maps (Fedora) or equivalent
- 5. Restart the GNOME session or logout/login to ensure the updated application is loaded

The advisory tells you what broke. It rarely tells you what actually worked. If you’ve dealt with this one, that detail is what the next engineer is searching for.

- A config change or rule that shut the vector down
- A gotcha in the upgrade path that cost you an afternoon
