MEDIUMHugo Markdown titles do not escaped in internal render hooks
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
Impact
Title argument in Markdown for links and images not escaped in internal render hooks. Impacted are Hugo users who have these hooks enabled and do not trust their Markdown content files.
Patches
Patched in v0.125.3.
Workarounds
Replace with user defined templates or disable the internal templates: https://gohugo.io/getting-started/configuration-markup/#renderhooksimageenabledefault

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/gohugoio/hugo. 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.
Fix
Update github.com/gohugoio/hugo to 0.125.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-ppf8-hhpp-f5hj is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-ppf8-hhpp-f5hj 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-ppf8-hhpp-f5hj. 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-ppf8-hhpp-f5hj in your dependencies?
O3 detects GHSA-ppf8-hhpp-f5hj across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
