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.

Description
Casdoor is a UI-first Identity and Access Management (IAM) / Single-Sign-On (SSO) platform. In Casdoor 1.577.0 and earlier, he purchase URL that is created to generate a WechatPay QR code is vulnerable to reflected XSS. When purchasing an item through casdoor, the product page allows you to pay via wechat pay. When using wechat pay, a QR code with the wechat pay link is displayed on the payment page, hosted on the domain of casdoor. This page takes a query parameter from the url successUrl, and redirects the user to that url after a successful purchase. Because the user has no reason to think that the payment page contains sensitive information, they may share it with other or can be social engineered into sending it to others. An attacker can then craft the casdoor link with a special url and send it back to the user, and once payment has gone though an XSS attack occurs.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/casdoor/casdoor. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of github.com/casdoor/casdoor has shipped for GHSA-gv2p-4mvg-g32h 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 pinpoints whether GHSA-gv2p-4mvg-g32h is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-gv2p-4mvg-g32h. 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-gv2p-4mvg-g32h in your dependencies?
O3 detects GHSA-gv2p-4mvg-g32h across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
