CVE-2026-72832 (GCVE-0-2026-72832)

Vulnerability from cvelistv5 – Published: 2026-08-14 11:35 – Updated: 2026-08-14 14:38

Title

Grav before 2.0.12 Stored XSS via quoted-attribute bypass

Summary

Grav versions from 1.5.2 through 2.0.12 contain a stored cross-site scripting vulnerability in the Security::detectXss() function (system/src/Grav/Common/Security.php). The event-handler scan is anchored at `<` and uses `[^>]*?`, which cannot cross the first literal `>`; when a `>` appears inside a quoted attribute value the browser keeps the tag open and parses a subsequent event handler (e.g. onerror), so the detector and browser disagree. A page editor without admin.super privileges can save page content such as `<img src=x title=">" onerror=alert(document.domain)>`, which is accepted, stored, and executed in the site origin when any visitor (including unauthenticated users) views the page. Fixed in 2.0.13.

The event-handler scan is anchored at `\u003c` and uses `[^\u003e]*?`, which cannot cross the first literal `\u003e`; when a `\u003e` appears inside a quoted attribute value the browser keeps the tag open and parses a subsequent event handler (e.g. onerror), so the detector and browser disagree. A page editor without admin.super privileges can save page content such as `\u003cimg src=x title=\"\u003e\" onerror=alert(document.domain)\u003e`, which is accepted, stored, and executed in the site origin when any visitor (including unauthenticated users) views the page.

Vulnerability from github – Published: 2026-09-17 17:28 – Updated: 2026-09-17 17:28

Summary

Grav: Stored XSS via quoted-attribute bypass in detectXss

Details

Summary

A page editor without admin.super can place an event handler after a > inside a quoted attribute. Grav accepts and stores the page, then executes the handler in the application origin when a visitor opens it.

Details

Security::detectXss() (system/src/Grav/Common/Security.php:253) anchors the on_events scan at < and uses [^>]*?, which cannot cross the first literal >. When that character is inside a quoted value, the browser keeps the tag open and parses the later onerror attribute, so the detector and browser disagree. AdminController::savePage() relies on this detector when saving content from page editors outside the admin.super whitelist.

PoC

I reproduced this with getgrav/grav 2.0.11 (ad9709f865b09b68798fb1ac375b484a8cc1d892), Admin 1.10.52, and Quark 2 1.1.4.

Sign in as a user with admin.login and admin.pages, but without admin.super.
Create or edit /xsstest and save this page body:

<img src=x title=">" onerror=alert(document.domain)>

Open /xsstest in a private browser window.

The save succeeds and the visitor sees an alert containing the site domain. With the body changed to <img src=x onerror=alert(1)>, the same endpoint rejects it with XSS issue detected and does not store it.

Impact

A page editor can execute JavaScript in the origin of every user who views the stored page, including unauthenticated visitors.

Anticipated objection and response

Although the detectXss() docblock describes it as a heuristic that cannot catch every XSS, this check is the storage-time boundary for page editors outside the default security.xss_whitelist of admin.super. The same endpoint rejects a plain handler but accepts this executable form, allowing a lower-trust editor to cross the boundary the check is intended to enforce.

Suggested fix

Prefer an HTML tokenizer or sanitizer that rejects event-handler attributes on parsed elements. If the existing tripwire remains, make its tag scan quote-aware instead of treating every > as a boundary. Add double-quoted and single-quoted regression cases plus the rejected plain-handler control.

Severity

5.4 (Medium)

Summary

Duplicate Advisory: Grav: Stored XSS via quoted-attribute bypass in detectXss

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-269c-h76q-8cxw. This link is maintained to preserve external references.

Original Description

Grav versions from 1.5.2 through 2.0.12 contain a stored cross-site scripting vulnerability in the Security::detectXss() function (system/src/Grav/Common/Security.php). The event-handler scan is anchored at < and uses [^>]*?, which cannot cross the first literal >; when a > appears inside a quoted attribute value the browser keeps the tag open and parses a subsequent event handler (e.g. onerror), so the detector and browser disagree. A page editor without admin.super privileges can save page content such as <img src=x title=">" onerror=alert(document.domain)>, which is accepted, stored, and executed in the site origin when any visitor (including unauthenticated users) views the page. Fixed in 2.0.13.

  "details": "### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-269c-h76q-8cxw. This link is maintained to preserve external references.\n\n### Original Description\nGrav versions from 1.5.2 through 2.0.12 contain a stored cross-site scripting vulnerability in the Security::detectXss() function (system/src/Grav/Common/Security.php). The event-handler scan is anchored at `\u003c` and uses `[^\u003e]*?`, which cannot cross the first literal `\u003e`; when a `\u003e` appears inside a quoted attribute value the browser keeps the tag open and parses a subsequent event handler (e.g. onerror), so the detector and browser disagree. A page editor without admin.super privileges can save page content such as `\u003cimg src=x title=\"\u003e\" onerror=alert(document.domain)\u003e`, which is accepted, stored, and executed in the site origin when any visitor (including unauthenticated users) views the page. Fixed in 2.0.13.",

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
