      <title>CVE-2026-55247 — plone.app.event: Denial of service via iCalendar import</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-55247</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; plone.app.event&lt;/p&gt;
&lt;p&gt;plone.app.event provides the event content type for Plone. Prior to versions 5.2.4 and 6.0.1, the iCalendar import in src/plone/app/event/ical/importer.py accepts insufficiently restricted calendar and event URLs, does not adequately bound downloaded bytes or imported events, and commits work per event. A logged-in editor can make the server request internal network resources or local calendar files, exhaust resources and take the site offline, and store a malicious event URL that executes script in another user&amp;#39;s browser. The fix restricts accepted URLs, applies MAXIMUM_ICAL_IMPORT_SIZE_BYTES and MAXIMUM_ICAL_IMPORT_EVENTS limits, uses transaction savepoints, and validates event URLs. This issue is fixed in versions 5.2.4 and 6.0.1.&lt;/p&gt;</description>
