Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-31098 is a weak password requirements vulnerability in Apache InLong, affecting versions 1.1.0 through 1.6.0. The flaw permits users to set passwords consisting of any characters or symbols without enforced complexity, directly exposing accounts to guessing attacks as described under CWE-521.

An unauthenticated remote attacker can exploit the issue over the network by guessing simple passwords chosen by users, achieving full account compromise with impacts to confidentiality, integrity, and availability. The vulnerability carries a CVSS 3.1 score of 9.8, reflecting that no authentication or user interaction is required for exploitation.

Apache advisories recommend upgrading to InLong 1.7.0 or applying the fix from pull request 7805 to enforce stronger password policies and resolve the weakness.

The associated EPSS score rose from a low baseline to a peak of 0.0800 on 2025-01-22 before receding to the current value of 0.0047, indicating a period of increased exploitation interest after disclosure.
