A cross-site scripting (XSS) vulnerability in the Attributes extension of the league/commonmark library (versions 1.5.0 through 2.6.x) allows remote attackers to insert malicious JavaScript calls into HTML. The league/commonmark library provides configuration options such as `html_input: 'strip'` and `allow_unsafe_links: false` to mitigate cross-site scripting (XSS) attacks by stripping raw HTML and disallowing unsafe links. However, when the Attributes Extension is enabled, it introduces a way for users to inject arbitrary HTML attributes into elements via Markdown syntax using curly braces. Version 2.7.0 contains three changes to prevent this XSS attack vector: All attributes starting with `on` are considered unsafe and blocked by default; support for an explicit allowlist of allowed HTML attributes; and manually-added `href` and `src` attributes now respect the existing `allow_unsafe_links` configuration option. If upgrading is not feasible, please consider disabling the `AttributesExtension` for untrusted users and/or filtering the rendered HTML through a library like HTMLPurifier.\n\ud83d\udccf Published: 2025-05-05T19:52:59.521Z\n\ud83d\udccf Modified: 2025-05-05T19:52:59.521Z\n\ud83d\udd17 References:\n1. https://github.com/thephpleague/commonmark/security/advisories/GHSA-3527-qv2q-pfvx\n2. https://github.com/thephpleague/commonmark/commit/f0d626cf05ad3e99e6db26ebcb9091b6cd1cd89b", "url": "https://t.me/DarkWebInformer_CVEAlerts/14988"}, {"timestamp": "2025-05-05T20:40:36Z", "date_only": false, "value": "2025-05-05T20:40:36Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-3527-QV2Q-PFVX", "record": "GHSA-3527-QV2Q-PFVX", "field": "published"}, {"timestamp": "2025-05-06T00:15:15Z", "date_only": false, "value": "2025-05-06T00:15:15.000000Z", "kind": "sighting", "label": "Seen", "source": "https://t.me/cvedetector/24505", "record": "CVE-2025-46734", "field": "creation_timestamp", "uuid": "f74d1c16-87c4-4cdc-82e7-3c0b2f936ea8", "content": "{\n  \"Source\": \"CVE FEED\",\n  \"Title\": \"CVE-2025-46734 - League Commonmark Attributes Extension Cross-Site Scripting Vulnerability\", \n  \"Content\": \"CVE ID : CVE-2025-46734 \nPublished : May 5, 2025, 8:15 p.m. | 1\u00a0hour, 25\u00a0minutes ago \nDescription : league/commonmark is a PHP Markdown parser.
