Compensating controls
- Validate the affected product branch and deploy the verified fixed release.
- Restrict the affected network interface to trusted sources where business-safe.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs ail-project ail-framework and falls inside the recorded affected range.
- Verify the installed build against the product-specific fixed version after deployment.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.

What, why and how
AIL Framework contains a server-side request forgery (SSRF) vulnerability in its crawler submission functionality. A low-privileged authenticated user with access to the crawler interface can submit an arbitrary URL for crawling without adequate validation of the destination host. The crawler can therefore be instructed to make direct HTTP(S) requests to addresses that should not be reachable by application users, including loopback addresses, RFC1918 private networks, link-local addresses, and cloud metadata services such as 169.254.169.254. Manual crawler tasks bypass the existing domain blacklist because they are assigned a non-zero priority, and ordinary IP literals are classified as web targets and fetched directly rather than through Tor or another proxy. Consequently, an attacker can use the AIL server as a network pivot to access services available from the server's network context. Responses generated by these requests, including captured HTML, screenshots, and HAR data, can subsequently be accessed through the crawler interface. This makes the SSRF non-blind and may allow an attacker to disclose sensitive internal application data, service information, or cloud instance metadata and credentials. The patch introduces validation that resolves crawler destinations and rejects URLs resolving to non-global IP addresses, addressing localhost, private-network, and link-local targets.

Why
The server follows an attacker-influenced destination, allowing requests to systems or services the attacker cannot reach directly.
How
An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
- Likely attack path
- a network path → Server-Side Request Forgery (SSRF) → cause the confidentiality, integrity or availability impact described by the vendor
- Attack surface
- Network
- Privileges required
- Low: a basic authenticated account is required
- User interaction
- None
- Attack complexity
- Low: no specialised conditions are recorded
- Security boundary
- Not a CVSS 4.0 base metric
- Weakness
?
CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-918 ↗
CWE-918: Server-Side Request Forgery (SSRF). The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
- CVSS vector
?
CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity. CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:L/SI:N/SA:NCommon Vulnerability Scoring System 4.0: the compact vector below is decoded into plain language.

- Stolen credentials, tokens and legitimate administration functions may provide continued access without deploying a large custom toolset.

Patch and workaround
Operational remediation based on structured source evidence.
- Status
?
Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change. - Patch available
- Affected
- ail-framework: < 7.0
- Action
- Review the linked authoritative reference and apply the recorded fixed release appropriate to the affected product branch.
- Workaround
- No verified workaround is recorded. If business-safe, reduce exposure to the affected interface and allow only trusted sources until authoritative guidance is available.
