EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-r9cr-hvjj-496v plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,166 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Impact
All unpatched versions of Argo CD starting with v1.3.0 are vulnerable to a path traversal bug, compounded by an improper access control bug, allowing a malicious user with read-only repository access to leak sensitive files from Argo CD's repo-server.
A malicious Argo CD user who has been granted get access for a repository containing a Helm chart can craft an API request to the /api/v1/repositories/{repo_url}/appdetails endpoint to leak the contents of out-of-bounds files from the repo-server.
The malicious payload would reference an out-of-bounds file, and the contents of that file would be returned as part of the response. Contents from a non-YAML file may be returned as part of an error message. The attacker would have to know or guess the location of the target file.
Sensitive files which could be leaked include files from other Applications' source repositories (potentially decrypted files, if you are using a decryption plugin) or any secrets which have been mounted as files on the repo-server.
Patches
A patch for this vulnerability has been released in the following Argo CD versions:
- v2.3.0
- v2.2.6
- v2.1.11
The patches do two things:
- prevent path traversal
- limit
/api/v1/repositories/{repo_url}/appdetailsaccess to users who either A) have been granted Applicationcreateprivileges or B) have been granted Applicationgetprivileges and are requesting details for arepo_urlthat has already been used for the given Application
Workarounds
The only certain way to avoid the vulnerability is to upgrade.
To mitigate the problem, you can
- avoid storing secrets in git
- avoid mounting secrets as files on the repo-server
- avoid decrypting secrets into files on the repo-server
- carefully limit who has
getaccess for repositories

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/argoproj/argo-cd, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/argoproj/argo-cd to 2.1.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r9cr-hvjj-496v 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.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-r9cr-hvjj-496v can be triaged on real exposure rather than presence alone.
Tailored to GHSA-r9cr-hvjj-496v. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
