Malcolm's front nginx reverse proxy defines a "Dashboards → Arkime shortcut" location using a case-insensitive regex matcher but a case-sensitive rewrite. A request whose path segment is not exact-lowercase (for example /IDDASH2ARK/...) enters the location (the matcher fires) but evades the rewrite (no redirect is issued), so nginx falls through to the location's proxypass to the Arkime backend. That location is the one proxied location in the shipped config that does not include the per-location authentication file, so the request reaches Arkime unauthenticated. The same location also forwards a client-supplied X-Forwarded-User header un-overwritten, and Arkime is configured to trust X-Forwarded-User as the authenticated username — so an unauthenticated network caller can reach the Arkime backend while supplying a forged, auto-provisioned identity.

A prior update that raised a bundled HTTP client library to a version remediating known vulnerabilities was later reverted, reintroducing the earlier, vulnerable version into a log-processing component. The only code path in that component using the library issues a request to a single fixed, trusted vendor URL at initialization and does not process attacker-controlled input through the library, limiting practical exploitability of the reintroduced version in this context.

A deployment mode intended to expose only read access to stored data proxies a set of application programming interface routes without restricting which request methods are allowed. One such route accepts a request that creates or overwrites a stored record, including an attacker-chosen identifier, using the application's own elevated backend credentials. This allows an authenticated user on a deployment intended to be read-only to forge or overwrite stored records that should not be modifiable in that deployment mode.

A web interface reflects a portion of the request URL into a script context and a hyperlink attribute without adequate encoding, and does not require authentication to reach. This allows an unauthenticated network attacker to craft a link that, when visited by a user, executes arbitrary script in the context of the affected application and can redirect the user's browser to an arbitrary external site. Successful exploitation could allow an attacker to act with the compromised user's session privileges within the application.

manage.get.gov is the .gov TLD registrar maintained by CISA. manage.get.gov allows an organization administrator to assign domain manager privileges for domains not already in another organization. Fixed in 1.176.0 on or around 2026-04-30.

The CISA Software Acquisition Guide Supplier Response Web Tool before 2025-12-11 was vulnerable to cross-site scripting via text fields. If an attacker could convince a user to import a specially-crafted JSON file, the Tool would load JavaScript from the file into the page. The JavaScript would execute in the context of the user's browser when the user submits the page (clicks 'Next').

CISA Thorium uses '.unwrap()' to handle errors related to account verification email messages. An unauthenticated remote attacker could cause a crash by providing a specially crafted email address or response. Fixed in commit 6a65a27.

CISA Thorium accepts a stream split size of zero then divides by this value. A remote, authenticated attacker could cause the service to crash. Fixed in commit 89101a6.

CISA Thorium does not validate TLS certificates when connecting to Elasticsearch. An unauthenticated attacker with access to a Thorium cluster could impersonate the Elasticsearch service. Fixed in 1.1.2.

CISA Thorium does not properly invalidate previously used tokens when resetting passwords. An attacker that possesses a previously used token could still log in after a password reset. Fixed in 1.1.1.

CISA Thorium does not rate limit requests to send account verification email messages. A remote unauthenticated attacker can send unlimited messages to a user who is pending verification. Fixed in 1.1.1 by adding a rate limit set by default to 10 minutes.

CISA Thorium does not escape user controlled strings used in LDAP queries. An authenticated remote attacker can modify LDAP authorization data such as group memberships. Fixed in 1.1.1.

CISA Thorium does not adequately validate the paths of downloaded files via 'downloadephemeral' and 'downloadchildren'. A remote, authenticated attacker could access arbitrary files subject to file system permissions. Fixed in 1.1.2.

Industrial Control Systems Network Protocol Parsers (ICSNPP) - Ethercat Zeek Plugin versions d78dda6 and prior are vulnerable to out-of-bounds read during the process of analyzing a specific Ethercat packet. This could allow an attacker to crash the Zeek process and leak some information in memory.

Industrial Control Systems Network Protocol Parsers (ICSNPP) - Ethercat Zeek Plugin versions d78dda6 and prior are vulnerable to out-of-bounds write while analyzing specific Ethercat datagrams. This could allow an attacker to cause arbitrary code execution.

Industrial Control Systems Network Protocol Parsers (ICSNPP) - Ethercat Zeek Plugin versions d78dda6 and prior are vulnerable to out-of-bounds write in their primary analyses function for Ethercat communication packets. This could allow an attacker to cause arbitrary code execution.
