Admin authentication required (PR:H); scope changes as the server proxies requests to subsequent internal systems (S:C); full response body returned yields high confidentiality impact; no integrity or availability impact.

DescriptionCVE.org

AVideo through version 27.0 contains a server-side request forgery vulnerability in plugin/Live/test.php that allows authenticated administrators to read arbitrary URLs via the statsURL parameter, which lacks isSSRFSafeURL() validation and accepts requests to private IP ranges and cloud metadata endpoints. Attackers can exploit this by crafting requests to internal services, cloud metadata endpoints like 169.254.169.254, and localhost to retrieve sensitive information including IAM credentials, internal service responses, and network configuration details.

AnalysisAI

Full-read SSRF in AVideo through version 27.0 allows authenticated administrators to make the server fetch arbitrary URLs via the statsURL parameter in plugin/Live/test.php, including cloud metadata endpoints and internal network services. The endpoint bypasses the codebase's own isSSRFSafeURL() guard - used in seven other endpoints - and returns full response bodies in the HTML output, enabling retrieval of IAM credentials from cloud metadata services such as 169.254.169.254, internal service data, and network configuration details. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Obtain AVideo admin credentials
Delivery
Authenticate to AVideo admin session
Exploit
Send statsURL=http://169.254.169.254/... to plugin/Live/test.php
Execution
Server fetches metadata endpoint without SSRF validation
Persist
Read IAM credentials from HTML response
Impact
Authenticate to cloud APIs with stolen credentials

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid AVideo administrator account - not a regular user account. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N) scores 6.1, reflecting that exploitation is network-accessible and low-complexity but gated behind high-privilege authentication (admin credentials), with all confidentiality impact classified as subsequent-system rather than vulnerable-system impact - meaning the exposed data belongs to downstream services, not AVideo itself. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained AVideo administrator credentials - through phishing, credential stuffing, or a compromised admin workstation - sends a crafted POST request to plugin/Live/test.php with statsURL set to http://169.254.169.254/latest/meta-data/iam/security-credentials/. The server-side fetch executes without DNS resolution checks, the full cloud metadata response is returned in the HTML output, and the attacker extracts temporary IAM access keys, secret keys, and session tokens sufficient to authenticate to AWS, GCP, or Azure APIs with the instance's assigned role permissions. …
Remediation The upstream fix commit c95eafbdfccd5959c546a430c32fb3b6026f39ac on the WWBN/AVideo GitHub repository patches the vulnerable endpoint; however, as of the time of this analysis, no tagged release incorporating this commit has been confirmed - the Composer package lists 'fixed in: None', making this an upstream fix available via commit only. … Detailed patch versions, workarounds, and compensating controls in full report.
