GHSA-79mg-4w23-4fqc is a high-severity (CVSS 8.1) SQL Injection vulnerability in cachethq/cachet. 2 public exploit references exist, so weaponization risk is real. No vendor fix is recorded yet; mitigation options are listed below.
Unauthenticated SQL Injection in Cachet
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-79mg-4w23-4fqc 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 378,567 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.
Real-World Exposure
cachethq/cachetReal-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
Impact
In Cachet versions through 2.3.18, there is a SQL injection which is in the SearchableTrait#scopeSearch(). Attackers without authentication can utilize this vulnerability to exfiltrate sensitive data from the database such as administrator's password and session.
Patches
The original repository of https://github.com/CachetHQ/Cachet is not active, the stable version 2.3.18 and it's developing 2.4 branch is affected.
Update to version 2.5 or later in the https://github.com/fiveai/Cachet fork to fix this vulnerability.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cachethq/cachet, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of cachethq/cachet has shipped for GHSA-79mg-4w23-4fqc yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-79mg-4w23-4fqc can be triaged on real exposure rather than presence alone.
Tailored to GHSA-79mg-4w23-4fqc. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
How to detect GHSA-79mg-4w23-4fqc
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:
