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.
  • CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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-7cqv-qcq2-r765 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.

Description

Summary

The server trusts all reverse-proxy headers by default, so any remote client can spoof X-Forwarded-For to bypass IP-based protections (AllowIPs, API IP whitelist, “localhost-only” checks). All IP-based access control becomes ineffective.

Details

  • Gin is created with defaults (gin.Default()), which sets TrustedProxies = 0.0.0.0/0 and uses X-Forwarded-For/X-Real-IP to compute ClientIP().

  • IP-based controls rely on ClientIP():

    • AllowIPs / BindDomain (core/middleware/ip_limit.go, core/utils/security/security.go).
    • API IP whitelist (core/middleware/api_auth.go).
    • "localhost-only" checks that depend on ClientIP().
  • Because no trusted-proxy range is enforced, any client can send X-Forwarded-For: 127.0.0.1 (or a whitelisted IP) and be treated as coming from that address.

Impact

All IP-based access control is rendered ineffective: remote clients can masquerade as localhost or any whitelisted IP, defeating AllowIPs, API IP whitelists, and “localhost-only” protections.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/1Panel-dev/1Panel, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/1Panel-dev/1Panel to 2.0.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7cqv-qcq2-r765 is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-7cqv-qcq2-r765 can be triaged on real exposure rather than presence alone.

Tailored to GHSA-7cqv-qcq2-r765. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
