How severe is GHSA-h8gc-pgj2-vjm3?

GHSA-h8gc-pgj2-vjm3 has a CVSS score of 5.9/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-h8gc-pgj2-vjm3?

GHSA-h8gc-pgj2-vjm3 affects the following packages: django (PyPI), django (PyPI), django (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-h8gc-pgj2-vjm3?

Update django to 3.2.22 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h8gc-pgj2-vjm3 is resolved across your whole dependency graph.

How do I detect GHSA-h8gc-pgj2-vjm3 in my PyPI dependencies?

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

How do I mitigate GHSA-h8gc-pgj2-vjm3 if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is GHSA-h8gc-pgj2-vjm3 actively exploited in the wild?

No public exploit code has been indexed for GHSA-h8gc-pgj2-vjm3 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-h8gc-pgj2-vjm3?

GHSA-h8gc-pgj2-vjm3 has an EPSS (Exploit Prediction Scoring System) score of 1.5%, placing it in the 74th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-h8gc-pgj2-vjm3?

GHSA-h8gc-pgj2-vjm3 is classified as CWE-1284 (CWE-1284). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-h8gc-pgj2-vjm3 published, and has it been updated?

GHSA-h8gc-pgj2-vjm3 was published on November 3, 2023 and was last updated on November 4, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

In Django 3.2 before 3.2.22, 4.1 before 4.1.12, and 4.2 before 4.2.6, the django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

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.
