CVE-2026-19781 Sep 15, 18:04 HIGH This Week

Heap-based buffer overflow in Ashlar-Vellum Cobalt during parsing of VS drawing files allows an attacker to execute arbitrary code in the context of the victim's process. Exploitation requires the target to open a crafted VS file (user interaction), and no authentication or server-side access is needed because the flaw sits in the file parser. No public exploit code has been identified and the issue is not listed in CISA KEV; the vendor advisory is ZDI-26-587.

CVE-2025-65088 May 12, 20:27 HIGH This Week

Arbitrary code execution and information disclosure in the Ashlar-Vellum CAD/3D-modeling suite (Cobalt, Xenon, Argon, Lithium, and Cobalt Share, versions 12.6.1204.216 and prior) can be triggered when the application parses a maliciously crafted VC6 file. The flaw is an out-of-bounds read (CWE-125) reached through the file-import path, giving an attacker who convinces a user to open a booby-trapped file the ability to leak memory or run code in the context of the victim. There is no public exploit identified at time of analysis and EPSS is negligible (0.01%), consistent with the local, user-interaction-dependent attack model reported by CISA ICS-CERT.

CVE-2025-65087 May 12, 20:25 HIGH This Week

Arbitrary code execution and information disclosure in Ashlar-Vellum's CAD suite (Cobalt, Xenon, Argon, Lithium, and Cobalt Share, versions 12.6.1204.216 and prior) is possible when the application parses a specially crafted VC6 file, driven by an out-of-bounds read (CWE-125). An attacker who convinces a user to open a malicious VC6 file can read out-of-bounds memory to leak data or steer execution toward running arbitrary code in the context of the user. There is no public exploit identified at time of analysis, the EPSS score is negligible (0.01%), and CISA's SSVC framework rates exploitation as 'none' but technical impact as 'total'.

CVE-2025-11465 Oct 29, 20:15 HIGH This Week

Parsing a maliciously crafted CO design file in Ashlar-Vellum Cobalt 12.2.1204.97 (the version identified in the CPE data) can trigger a use-after-free that allows arbitrary code execution in the context of the user running the application. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, 7.8) shows the flaw is reachable without authentication (PR:N) but is not remotely reachable as a service: it is a local-vector issue that requires mandatory user interaction, meaning the victim must open the file or visit a page that serves it, and any code runs at the privileges of the current, normally non-elevated user (no scope change). Reported through Trend Micro's Zero Day Initiative as ZDI-CAN-26631 / ZDI-25-956, the issue has no confirmed active exploitation (not in CISA KEV) and no public exploit code identified at time of analysis; EPSS is low at 0.21% (11th percentile), consistent with a targeted, file-delivery-dependent client-side bug rather than a mass-exploited one.

Integer overflow in the XE file-parsing routine of Ashlar-Vellum Cobalt 12.2.1204.97 lets an attacker execute arbitrary code in the context of the running process when a user opens a maliciously crafted XE file or visits a page that delivers one. Because the flaw is reached through local file parsing (AV:L) and requires the victim to be socially engineered into opening attacker-supplied content (UI:R), it is a genuine but non-urgent risk: there is no network-reachable attack surface independent of user action, and code runs only with the privileges of the user running Cobalt, with no scope change. No public exploit code has been identified at time of analysis, the vulnerability is not confirmed actively exploited (no CISA KEV listing), and EPSS is low at 0.20% (9th percentile), reflecting limited observed exploitation activity.
