Real-World Exposure
francoisjacquet/rosariosisReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
RosarioSIS prior to 11.0 allows anyone, regardless of authentication status, to download and view file attachments under the salaries module. In addition, the file names contain a date in a YYYY-MM-DD format and a random six-string digit, making enumerating file names with automated tools relatively easy. This could allow an attacker to gain access to sensitive salary information. The patch for version 11.0 adds microseconds to filenames to make them harder to guess.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for francoisjacquet/rosariosis, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update francoisjacquet/rosariosis to 11.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-2665 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
