CVSS 9.6 ยท Critical

Q1What is this vulnerability? (Essence + Consequences)

๐Ÿšจ **Essence**: OpenC3 COSMOS Script Runner allows users to run Python/Ruby scripts. ๐ŸŒ **Consequence**: Scripts bypass API checks to access the shared Docker network.โ€ฆ

Q2Root Cause? (CWE/Flaw)

๐Ÿ›ก๏ธ **CWE**: CWE-250 (Execution of Code with unnecessary privileges). ๐Ÿ” **Flaw**: Lack of network isolation between the Script Runner container and other services (Redis, Buckets).โ€ฆ

Q3Who is affected? (Versions/Components)

๐Ÿ“ฆ **Vendor**: OpenC3. ๐Ÿ“ฆ **Product**: COSMOS. ๐Ÿ“‰ **Affected**: Versions **before 7.0.0-rc3**. โœ… **Fixed**: In v7.0.0-rc3 and later.

Q4What can hackers do? (Privileges/Data)

๐Ÿ•ต๏ธ **Privileges**: Escalates from standard user to Admin-level access.โ€ฆ

Q5Is exploitation threshold high? (Auth/Config)

๐Ÿ”‘ **Auth Required**: Yes. PR:L (Privileges Required: Low). ๐Ÿšซ **UI**: None required. โš ๏ธ **Threshold**: Any user with permission to **create and run scripts** can exploit this. No complex config needed.

Q6Is there a public Exp? (PoC/Wild Exploitation)

๐Ÿ“œ **Public Exp?**: No specific PoC provided in data. ๐ŸŒ **Wild Exploitation**: Low risk currently. ๐Ÿ“ **Note**: References point to GitHub release/advisory, but no active exploit code is listed in the provided data.

Q7How to self-check? (Features/Scanning)

๐Ÿ” **Check**: Look for OpenC3 COSMOS versions < 7.0.0-rc3. ๐Ÿงช **Test**: If you have script execution rights, check if you can reach Redis/Bucket services via the script runner container network.โ€ฆ

Q8Is it fixed officially? (Patch/Mitigation)

๐Ÿ”ง **Fixed**: Yes. ๐Ÿ“… **Patch Date**: Released 2026-05-04. ๐Ÿš€ **Action**: Upgrade to **v7.0.0-rc3** or **v7.0.0**. ๐Ÿ”— **Ref**: [GitHub Release](https://github.com/OpenC3/cosmos/releases/tag/v7.0.0-rc3).

Q9What if no patch? (Workaround)

๐Ÿ›‘ **Workaround**: Restrict script execution permissions to Admins only. ๐Ÿšซ **Network**: Isolate the Script Runner container from Redis/Bucket networks if possible.โ€ฆ

Q10Is it urgent? (Priority Suggestion)

โšก **Priority**: HIGH. ๐Ÿ“ˆ **CVSS**: 8.6 (High). ๐Ÿ“‰ **Vector**: AV:N/AC:L/PR:L/S:C/C:H/I:H/A:N. ๐Ÿšจ **Reason**: Low attack complexity, low privilege requirement, and high impact on confidentiality/integrity. Fix immediately.
