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-8xx5-h6m3-jr33 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.
Real-World Exposure
prestashop/prestashopReal-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
An unauthenticated attacker with access to the back-office URL can manipulate the id_employee and reset_token parameters to enumerate valid back-office employee email addresses.
Impacted parties: Store administrators and employees: their email addresses are exposed. Merchants: risk of phishing, social engineering, and brute-force attacks targeting admin accounts.
Patches
PrestaShop 8.2.3
Workarounds
You must upgrade, or at least apply the changes from the PrestaShop 8.2.3 patch. More information: https://build.prestashop-project.org/news/2025/prestashop-8-2-3-security-release/

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for prestashop/prestashop, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update prestashop/prestashop to 8.2.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8xx5-h6m3-jr33 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-8xx5-h6m3-jr33 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-8xx5-h6m3-jr33. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
