Impact
A successful SSRF attack allows an attacker to:
- Bypass firewalls to scan and interact with internal network services/ports.
- Access sensitive cloud metadata services (e.g., AWS IMDS 169.254.169.254) to potentially leak instance credentials.
- Pivot into the internal network environment where Postiz is hosted.
Workarounds
There are no workarounds known to this, please upgrade to Postiz version v2.21.1.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for postiz, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of postiz has shipped for GHSA-vj2p-7pgw-g2wf 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-vj2p-7pgw-g2wf can be triaged on real exposure rather than presence alone.
Tailored to GHSA-vj2p-7pgw-g2wf. 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-vj2p-7pgw-g2wf in your dependencies?
O3 Security finds GHSA-vj2p-7pgw-g2wf across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
