How do I fix GHSA-crvm-xjhm-9h29?

Update octoprint to 1.11.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-crvm-xjhm-9h29 is resolved across your whole dependency graph.

How do I detect GHSA-crvm-xjhm-9h29 in my PyPI dependencies?

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

How do I mitigate GHSA-crvm-xjhm-9h29 if there is no patch (or I can't update yet)?

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.

Is GHSA-crvm-xjhm-9h29 actively exploited in the wild?

No public exploit code has been indexed for GHSA-crvm-xjhm-9h29 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.

Description

Impact

OctoPrint versions up to and including 1.11.3 are affected by a vulnerability that allows injection of arbitrary HTML and JavaScript into Action Command notification and prompt popups generated by the printer.

An attacker who successfully convinces a victim to print a specially crafted file could exploit this issue to disrupt ongoing prints, extract information (including sensitive configuration settings, if the targeted user has the necessary permissions for that), or perform other actions on behalf of the targeted user within the OctoPrint instance.

Patches

The vulnerability will be patched in version 1.11.4.

Workaround

OctoPrint administrators can mitigate the risk by disabling popups:

for Action Command notifications, uncheck OctoPrint Settings -> Printer Notifications -> Enable popups
for Action Command prompts, set OctoPrint Settings -> Printer Dialogs -> Enable support -> Never

It is also strongly recommended to ensure that files being printed originate from trusted sources, and, whenever possible, are sliced with your own slicer.
