CVE-2026-105131: Incorrect Authorization in mayswind ezBookkeeping
Description
ezBookkeeping 1.2.0 before 2.0.1 contains a privilege escalation vulnerability that allows attackers holding an API token to obtain a full session token via /api/v1/tokens/refresh.json. Because TokenRefreshHandler never checks token type, attackers can exchange short-lived or IP-restricted API tokens for 30-day normal session tokens that bypass API token expiry and allowlists.

Technical Analysis
CVE-2026-105131 is a privilege escalation vulnerability in mayswind ezBookkeeping affecting versions >=1.2.0 and <2.0.1. The issue occurs because the TokenRefreshHandler endpoint /api/v1/tokens/refresh.json does not check the token type before refreshing tokens. Attackers with a short-lived or IP-restricted API token can exploit this to obtain a long-lived (30-day) normal session token, effectively bypassing token expiry and allowlists.
Potential Impact
An attacker with an API token can escalate privileges by obtaining a full session token that lasts 30 days, bypassing intended token expiration and IP restrictions. This could allow unauthorized access to the application with elevated privileges for an extended period.
