CVE-2026-111662 Details
Description
Chaskiq through 2.0.3 contains a server-side request forgery vulnerability that allows unauthenticated attackers to make the server fetch arbitrary URLs via the url parameter of the /oembed endpoint. Attackers can target loopback, private, or cloud-metadata addresses through FetchLinkCardService, which follows redirects and skips TLS verification, to read internal page titles and descriptions.
A server-side request forgery (SSRF) vulnerability has been identified in Chaskiq versions through 2.0.3. This vulnerability allows unauthenticated attackers to manipulate the server into fetching arbitrary URLs via the 'url' parameter of the '/oembed' endpoint. The 'FetchLinkCardService' processes these requests, following redirects and bypassing TLS verification, which could be exploited to access internal page metadata from loopback, private, or cloud-metadata addresses.
Chaskiq users should update to version 2.0.4 or later, where this vulnerability has been addressed.
