HIGHGHSA-jjxg-hpm7-g95f is a high-severity (CVSS 8.8) vulnerability in bzr. No vendor fix is recorded yet; mitigation options are listed below.
Bazaar allows remote attackers to execute arbitrary commands via a bzr+ssh URL with initial dash character in hostname
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-jjxg-hpm7-g95f 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
Bazaar through 2.7.0, when Subprocess SSH is used, allows remote attackers to execute arbitrary commands via a bzr+ssh URL with an initial dash character in the hostname, a related issue to CVE-2017-9800, CVE-2017-12836, CVE-2017-12976, CVE-2017-16228, CVE-2017-1000116, and CVE-2017-1000117.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for bzr, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of bzr has shipped for GHSA-jjxg-hpm7-g95f 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-jjxg-hpm7-g95f can be triaged on real exposure rather than presence alone.
Tailored to GHSA-jjxg-hpm7-g95f. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Frequently Asked Questions
Is GHSA-jjxg-hpm7-g95f in your dependencies?
O3 Security finds GHSA-jjxg-hpm7-g95f across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
