Vulnerability Assessment

Exploitation Conditions

Requires a valid authenticated session to the Absolute Secure Access server (CVSS PR:L) - exploitation is not available to unauthenticated attackers. Given that precondition, the flaw is reachable remotely over the network (AV:N), at low complexity (AC:L), with no user interaction (UI:N), and no special attack requirements (AT:N). The specific product feature, protocol endpoint, or configuration that must be reached to deliver the malformed input is not described in the available sources. The principal limiting factor is the authentication requirement; the principal aggravating factor is that the resulting denial of service is persistent (VA:H) rather than transient. Fixed in version 14.61 - all prior versions are affected; the vendor advisory presents upgrading as the remediation.

Impact

This is a medium-to-high severity, authenticated denial-of-service issue in Absolute Secure Access servers (CVSS 4.0 base 7.1). The supplied CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:L) indicates remote, low-complexity exploitation with no user interaction but requiring low-level privileges (PR:L) - so an attacker must already be authenticated. Impact is concentrated on availability (VA:H, persistent DoS) with only limited integrity impact (VI:L) and no confidentiality impact (VC:N). No EPSS score was provided, the CVE is not listed in CISA KEV, and no exploit or PoC reference is present in the input - so there is no public exploit identified at time of analysis. The vuln.today decision label is 'this_week', which signals meaningful but non-emergency urgency rather than act_now/emergency. Net: this is a genuine availability risk worth remediating on a near-term schedule, but the authentication requirement and the availability-only (non-RCE, non-data-exposure) impact place it below the tier of critical unauthenticated flaws. Note that CVSS asserts a network vector while the description does not describe the exact trigger mechanism - the precise input/feature that must be reached is not stated in the available sources.

Exploit ScenarioDerived

An attacker who already holds valid (low-privilege) credentials to an Absolute Secure Access server sends crafted or malformed input that the server handles improperly, driving it into a persistent denial-of-service state that survives beyond the request and disrupts service for all users. The CVSS AV:N/AC:L profile means this can be done remotely over the network with low effort once authenticated. No public exploit code was identified at time of analysis.

AnalysisAIv1 – Nov 02, 2026

Authenticated users of Absolute Secure Access servers running versions prior to 14.61 can supply improperly handled input that results in a persistent denial of service, leaving the service impaired beyond the initial request. The flaw is network-reachable at low complexity and requires no user interaction, but it does require a valid authenticated session (CVSS PR:L), so only accounts able to log in to the server can reach it. Absolute addresses the issue in 14.61; no public exploit code and no confirmed active exploitation were identified at time of analysis.

RemediationAI

Upgrade Absolute Secure Access server to version 14.61 or later, which is the remediation the vendor advisory presents; all earlier versions remain affected. The advisory at https://www.absolute.com/platform/security-information/vulnerability-archive/cve-2026-116767 should be consulted for the vendor's installation guidance and any version-specific notes. No compensating controls or workarounds are described in the available sources, and because exploitation requires a valid authenticated session, the only documented fix path is applying the 14.61 release.

Technical ContextAI · show details

The root cause is classified as improper input handling in Absolute Secure Access server software, although no CWE identifier is provided in the available sources, so the specific parsing or validation weakness cannot be pinned to a defined weakness class. Per the assessed vector (AV:N/AC:L/PR:L/UI:N/AT:N), the defect is reachable over the network at low complexity by an attacker holding a valid authenticated session, with no user interaction and no additional attack requirements. Impact is availability-dominant: the denial of service is persistent rather than transient (VA:H) with a limited integrity effect (VI:L) and no confidentiality impact, and the CVSS 4.0 vector additionally records limited subsequent-system availability impact (SA:L). The exact product feature, protocol endpoint, or configuration required to deliver the malformed input is not described in the available sources, and the trigger mechanism is therefore unverified. The CPE string cpe:2.3:a:absolute_software:secure_access confirms the affected platform is Absolute Software Secure Access across all versions in the pre-14.61 range.
