Exploitation and automatability from CISA’s SSVC triage for GHSA-m988-7375-7g2c.
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-m988-7375-7g2c 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 379,145 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
pimcore/admin-ui-classic-bundleReal-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
The translation value with text including “%s” (from “%suggest%) is parsed by sprintf() even though it’s supposed to be output literally to the user.
The translations may be accessible by a user with comparatively lower overall access (as the translation permission cannot be scoped to certain “modules”) and a skilled attacker might be able to exploit the parsing of the translation string in the dialog box.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pimcore/admin-ui-classic-bundle, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update pimcore/admin-ui-classic-bundle to 1.1.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m988-7375-7g2c 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-m988-7375-7g2c can be triaged on real exposure rather than presence alone.
Tailored to GHSA-m988-7375-7g2c. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-m988-7375-7g2c in your dependencies?
O3 Security finds GHSA-m988-7375-7g2c across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
