Unauthenticated network SSRF with scope change to internal services; raised C to H because echoed 'auth' field directly exfiltrates credentials, no integrity/availability impact.

Lifecycle Timeline
2DescriptionCVE.org
The Kargo Takip plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.2 via the 'api_url' parameter. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. The script echoes internal API response data (specifically the value of any 'auth' key in a JSON response body) verbatim back to the attacker's browser, enabling direct exfiltration of responses from internal services such as cloud instance metadata endpoints.

AnalysisAI
Server-side request forgery in the Kargo Takip WordPress plugin (versions through 1.2) allows unauthenticated remote attackers to coerce the site into issuing arbitrary HTTP requests via the 'api_url' parameter and to exfiltrate data from internal services. Because the plugin echoes the value of any 'auth' key from the JSON response back to the attacker, it enables direct retrieval of sensitive responses such as cloud instance metadata credentials. No public exploit identified at time of analysis, and the plugin is not listed in CISA KEV.
Technical ContextAI
Kargo Takip is a Turkish-language shipment/cargo tracking plugin for WordPress (vendor 'bytuncay', CPE cpe:2.3:a:bytuncay:kargo_takip). The flaw resides in ui/decodeandview.php, which accepts a user-controlled 'api_url' parameter and uses it to perform a server-side HTTP request without validating the destination host or scheme. This is a textbook CWE-918 (Server-Side Request Forgery): the server acts as a confused deputy, reaching into network positions (loopback, RFC1918, link-local 169.254.169.254 metadata endpoints) the attacker cannot reach directly. The additional echoing of the JSON 'auth' field amplifies the impact from blind SSRF to a data-exfiltration primitive, since cloud metadata services such as AWS IMDSv1, GCP, and Azure return credentials in response bodies that can be parsed for an 'auth' key or otherwise reflected back.
RemediationAI
No vendor-released patch identified at time of analysis - the references point to the current trunk source of the vulnerable file, not a tagged fixed release. Until a fixed version is published, the most reliable remediation is to deactivate and uninstall the Kargo Takip plugin (trade-off: shipment/cargo tracking functionality is lost). If the plugin must remain enabled, restrict access to the decodeandview.php endpoint via WAF or web-server rules (e.g., block external requests to /wp-content/plugins/kargo-takip/ui/decodeandview.php, or filter requests carrying an 'api_url' parameter), and, for cloud-hosted WordPress instances, enforce IMDSv2 with hop-limit 1 and remove or scope down any attached IAM role to deny the WordPress host access to sensitive metadata (trade-off: legitimate workloads that rely on IMDSv1 must be reworked). Egress filtering from the WordPress host to RFC1918, loopback, and 169.254.169.254 further reduces SSRF blast radius. Monitor the Wordfence advisory page for an official fixed version.
