CVE-2026-39361 (GCVE-0-2026-39361)

Vulnerability from cvelistv5 – Published: 2026-04-07 19:02 – Updated: 2026-04-09 16:17

Title
OpenObserve has a SSRF Protection Bypass via IPv6 Bracket Notation in validate_enrichment_url
Summary
OpenObserve is a cloud-native observability platform. In 0.70.3 and earlier, the validate_enrichment_url function in src/handler/http/request/enrichment_table/mod.rs fails to block IPv6 addresses because Rust's url crate returns them with surrounding brackets (e.g. "[::1]" not "::1"). An authenticated attacker can reach internal services blocked from external access. On cloud deployments this enables retrieval of IAM credentials via AWS IMDSv1 (169.254.169.254), GCP metadata, or Azure IMDS. On self-hosted deployments it allows probing internal network services.

Title
InvenTree has SSRF via Remote Image Download — No IP/Hostname Validation on remote_image URLs
Summary
InvenTree is an Open Source Inventory Management System. Prior to 1.2.7 and 1.3.0, when INVENTREE_DOWNLOAD_FROM_URL is enabled (opt-in), authenticated users can supply remote_image URLs that are fetched server-side via requests.get() with only Django's URLValidator check. There is no validation against private IP ranges or internal hostnames. Redirects are followed (allow_redirects=True), enabling bypass of any URL-format checks. This vulnerability is fixed in 1.2.7 and 1.3.0.

CVE-2026-39368 (GCVE-0-2026-39368)

Vulnerability from cvelistv5 – Published: 2026-04-07 19:23 – Updated: 2026-04-07 20:02

Title
WWBN AVideo has a Live restream log callback flow enabling stored SSRF to internal services
Summary
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the Live restream log callback flow accepted an attacker-controlled restreamerURL and later fetched that stored URL server-side, enabling stored SSRF for authenticated streamers. The vulnerable flow allowed a low-privilege user with streaming permission to store an arbitrary callback URL and trigger server-side requests to loopback or internal HTTP services through the restream log feature.

Title
WWBN AVideo has an Allowlisted downloadURL media extensions bypass SSRF protection and enable internal response exfiltration (Incomplete fix for CVE-2026-27732)
Summary
WWBN AVideo is an open source video platform. In versions 26.0 and prior, objects/aVideoEncoder.json.php still allows attacker-controlled downloadURL values with common media or archive extensions such as .mp4, .mp3, .zip, .jpg, .png, .gif, and .webm to bypass SSRF validation. The server then fetches the response and stores it as media content. This allows an authenticated uploader to turn the upload-by-URL flow into a reliable SSRF response-exfiltration primitive. The vulnerability is caused by an incomplete fix for CVE-2026-27732.

CVE-2026-39383 (GCVE-0-2026-39383)

Title
Gotenberg unauthenticated blind SSRF via unfiltered webhook URL
Summary
Gotenberg is an API-based document conversion tool. In version 8.29.1, an unauthenticated attacker with network access can force the server to make outbound HTTP POST requests to arbitrary internal or external destinations by supplying a crafted URL in the Gotenberg-Webhook-Url request header. The FilterDeadline function in filter.go is intended to gate outbound URLs, but when both the allow-list and deny-list are empty (the default configuration), it returns nil unconditionally and permits any URL. This is a blind SSRF: Gotenberg POSTs the converted document to the webhook URL and only checks whether the response status code is an error, but never returns the target's response body to the attacker. An attacker can use this to probe internal network infrastructure by observing whether the error callback is invoked, force POST requests against internal services that perform side effects, and confirm reachability of cloud metadata endpoints. The retryable HTTP client issues up to 4 automatic retries per request, amplifying each probe. This issue has been fixed in version 8.31.0. As a workaround, configure the GOTENBERG_API_WEBHOOK_ALLOW_LIST environment variable to restrict webhook URLs to known receivers, or set GOTENBERG_API_WEBHOOK_DENY_LIST to block RFC-1918 and link-local address ranges.

          "value": "Gotenberg is an API-based document conversion tool. In version 8.29.1, an unauthenticated attacker with network access can force the server to make outbound HTTP POST requests to arbitrary internal or external destinations by supplying a crafted URL in the Gotenberg-Webhook-Url request header. The FilterDeadline function in filter.go is intended to gate outbound URLs, but when both the allow-list and deny-list are empty (the default configuration), it returns nil unconditionally and permits any URL. \n\nThis is a blind SSRF: Gotenberg POSTs the converted document to the webhook URL and only checks whether the response status code is an error, but never returns the target\u0027s response body to the attacker. An attacker can use this to probe internal network infrastructure by observing whether the error callback is invoked, force POST requests against internal services that perform side effects, and confirm reachability of cloud metadata endpoints. The retryable HTTP client issues up to 4 automatic retries per request, amplifying each probe.\n\nThis issue has been fixed in version 8.31.0. As a workaround, configure the GOTENBERG_API_WEBHOOK_ALLOW_LIST environment variable to restrict webhook URLs to known receivers, or set GOTENBERG_API_WEBHOOK_DENY_LIST to block RFC-1918 and link-local address ranges."

CVE-2026-39418 (GCVE-0-2026-39418)

Title
MaxKB: SSRF via sandbox network hook bypass
Summary
MaxKB is an open-source AI assistant for enterprise. In versions 2.7.1 and below, sandbox network protection can be bypassed by using socket.sendto() with the MSG_FASTOPEN flag. This allows authenticated user with tool-editing permissions to reach internal services that are explicitly blocked by the sandbox's banned hosts configuration. MaxKB's sandbox uses LD_PRELOAD to hook the connect() function and block connections to banned IPs, but Linux's sendto() with the MSG_FASTOPEN flag can establish TCP connections directly through the kernel without ever calling connect(), completely bypassing the IP validation. Although sendto is listed in the syscall() wrapper, this is ineffective because glibc invokes the kernel syscall directly rather than routing through the hooked syscall() function. This issue has been fixed in version 2.8.0.

CAPEC-664: Server Side Request Forgery

An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
