Chaskiq Unauthenticated SSRF via /oembed Endpoint

Sources read

Source agreement

0/2

Evidence confidence

%44

Short explanation

Chaskiq through version 2.0.3 contains a server-side request forgery (SSRF) vulnerability via the url parameter of the /oembed endpoint. This unauthenticated flaw allows attackers to read internal page titles and descriptions.

Why does it matter?

This unauthenticated SSRF vulnerability allows attackers to target loopback, private, or cloud-metadata addresses. Due to FetchLinkCardService following redirects and skipping TLS verification, internal data exposure risks are significantly increased.

What should be done?

Follow vendor advisories for updates
Upgrade the application to a non-affected version
Validate input supplied to the url parameter in the /oembed endpoint

Show the technical text from the sources

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.
