GHSA-hrgx-p36p-89q4 is a critical-severity (CVSS 9.8) CWE-74 vulnerability in prestashop/prestashop. 1 public exploit reference exists, so weaponization risk is real. A fix is available for prestashop/prestashop — see the affected versions and patch details below.
PrestaShop eval injection possible if shop vulnerable to SQL injection
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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-hrgx-p36p-89q4 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.

Description
Impact
Eval injection possible if the shop is vulnerable to an SQL injection.
Patches
The problem is fixed in version 1.7.8.7
Workarounds
Delete the MySQL Smarty cache feature by removing these lines in the file config/smarty.config.inc.php lines 43-46 (PrestaShop 1.7) or 40-43 (PrestaShop 1.6):
if (Configuration::get('PS_SMARTY_CACHING_TYPE') == 'mysql') {
include _PS_CLASS_DIR_.'Smarty/SmartyCacheResourceMysql.php';
$smarty->caching_type = 'mysql';
}

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 1.7.8.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hrgx-p36p-89q4 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-hrgx-p36p-89q4 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-hrgx-p36p-89q4. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
How to detect GHSA-hrgx-p36p-89q4
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:
nuclei -id ghsa-hrgx-p36p-89q4 -u https://target- Template
- PrestaShop - SQL Injection to Eval Injection
- Severity
- critical
- Impact
- Attackers can execute arbitrary PHP code, leading to remote code execution and full system compromise
- Remediation
- Upgrade to version 1.7.8.7 or later. Alternatively, delete the MySQL Smarty cache feature if upgrade is not possible.
