CVE-2026-44188 | Ansible-lightspeed: ansible lightspeed: session hijacking and unauthorized data access due to insufficient session expiration

A flaw was found in Ansible Lightspeed. This vulnerability, related to insufficient session expiration, allows a remote attacker to maintain persistent access to the Ansible Lightspeed instance. If an attacker exfiltrates a valid OAuth (Open Authorization) access token before a user logs out, they can continue to authenticate and access sensitive data. This is because the application fails to invalidate the token on the backend, leaving it valid until its natural expiration. This can lead to unauthorized read access to Ansible resources such as inventories, playbooks, and configuration data.

Base score Version Severity Vector Exploitability Impact Score source
5.3 3.1 MEDIUM
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
