knowns through 0.33.0 contains a server-side request forgery vulnerability in the POST /api/embedding-models/test endpoint that issues outbound requests to caller-supplied destinations without validation. Attackers can enumerate internal hosts and cloud metadata endpoints by observing transport error messages that reveal network reachability information.

CVE-2026-82757——
———Server-Side Request Forgery (SSRF) vulnerability in ash-project ash_authentication_oauth2_server allows an attacker who controls a client metadata URL and its DNS to make the server connect to internal or loopback addresses.
public_ip?/1 in AshAuthentication.Oauth2Server.CIMD.ReqFetcher enforces the outbound policy for CIMD metadata fetches. It classified several address forms as publicly routable that are not: IPv4-compatible ::/96 (for example ::127.0.0.1), SIIT IPv4-translated ::ffff:0:0:0/96, and deprecated site-local fec0::/10. A returned AAAA record in one of these ranges passed the policy, so a fetch pinned to that address reached space the policy was meant to block.
This issue affects ash_authentication_oauth2_server: from 0.3.0 before 0.3.1.5hCVE-2026-865033.3 BAJ—
———In JetBrains IntelliJ IDEA before 2026.2.2 opening an untrusted project could trigger SSRF via Kubernetes spec-source URL fetching11hCVE-2026-863215.3 MED—
———A vulnerability was found in java-json-tools jackson-coreutils 2.0. Affected by this issue is the function JsonLoader.fromURL of the file src/main/java/com/github/fge/jackson/JsonLoader.java of the component URL Validation. The manipulation results in server-side request forgery. It is possible to launch the attack remotely. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.12hCVE-2026-86419——
———Affected versions of MISP contain insufficient validation of server-side outbound HTTP destinations in feed retrieval and TAXII discovery functionality.
In feed processing, redirects were followed without validating the redirect scheme or destination. The original request headers were reused across redirect hops, meaning authentication headers or API credentials configured for a feed could be forwarded to a different host. Redirects could also target internal network resources, resulting in SSRF. The fix adds redirect validation, blocks internal destinations for cross-host redirects, strips configured feed credentials before following redirects to another host, and pins validated DNS results to prevent re-resolution after validation.
The TAXII discovery endpoint had a related incomplete SSRF defense. It used gethostbyname() and compared the result against only a few literal addresses. This missed cases including IPv6 loopback (::1), numeric host encodings such as 0x7f000001, and potentially multiple DNS records. The fix moves TAXII discovery to the shared URL egress validator.
Together, these commits harden MISP's outbound URL handling against alternate-address representations, DNS-related bypasses, unsafe redirects, internal-host access, and cross-host credential forwarding.

——0A weakness has been identified in projeto-siga siga up to 11.1.1. Affected by this issue is the function DownloadExterno.getUrl of the file sigaex/src/main/java/br/gov/jfrj/siga/vraptor/ExUtilController.java of the component HTML-to-PDF Endpoint. This manipulation of the argument html causes server-side request forgery. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.22hCVE-2026-862404.7 MED—
——0A security flaw has been discovered in liufee FeehiCMS up to 2.1.1. This affects the function catchImage of the file backend/widgets/ueditor/Uploader.php of the component UEditor. The manipulation of the argument source[] results in server-side request forgery. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.1d
