Buffer overflow in LinkingVision rapidvms

IdentifiersCVE-2026-33849CWE-119· Improper Restriction of Operations…

CVE-2026-33849 is an improper restriction of operations within the bounds of a memory buffer in LinkingVision rapidvms. The available information indicates a buffer overflow class vulnerability affecting rapidvms versions before PR#96. No specific vulnerable function, code path, or triggering component is identified in the provided content. The associated CVSS v3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) indicates the flaw is reachable over the network, requires low attack complexity, does not require privileges, and requires user interaction.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation could result in high impact to confidentiality, integrity, and availability. Based on the vulnerability class and CVSS assessment, exploitation may allow memory corruption leading to application crash, denial of service, unauthorized modification of data or process behavior, and potentially arbitrary code execution or comparable compromise of the affected rapidvms process. The precise technical impact is not further specified in the provided content.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure of rapidvms network-accessible interfaces to trusted users and networks only, and minimize or eliminate user interaction with untrusted content or inputs that may reach the vulnerable component. Apply compensating controls such as network segmentation, reverse-proxy filtering, strict access controls, and monitoring for crashes or anomalous behavior in rapidvms until the patched version can be deployed. Specific mitigations beyond patching are not provided in the available content.

Remediation

Patch, then assume compromise.

Upgrade LinkingVision rapidvms to a version that includes the fix associated with pull request #96. Versions before PR#96 are affected; the remediation is to deploy the patched release incorporating that change and verify the vulnerable code path is no longer reachable in production.
