3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked

A newly published CVE, CVE-2026-116366, affects ClickHouse Server, the open-source database system. Under certain conditions, an unauthenticated attacker with network access could execute arbitrary code on the server. CISA's assessment rates it as non-automatable with total technical impact, and no public exploit is listed.

Read the original at cve.now. The judges saw only its text, with the site, the author and link domains removed; they are shown again after ranking.

Why it ranked

No. 111 of 111 with a score of 0.58. The panel rated it highest on new information (0.90) and practical relevance (0.72), lowest on technical depth (0.28). Placed No. 111, No. 77 by score alone: the 34th Security story of the day (−0.080), and close to “ClickHouse – RCE – CVE-2026-116366”, No. 44 today (−0.043). The placement terms move stories; they are not part of the score.

AI judgeJudge 2claude-haiku-5-5
Security advisory for widely used ClickHouse database with unauthenticated RCE and fixed versions listed; advisory-only, no technical exploit detail, conditions unspecified, so moderate significance and low depth.
AI judgeJudge 3gpt-5.6-luna
A newly published unauthenticated RCE in a widely used database is operationally important, with explicit affected and fixed versions. However, the advisory provides little technical detail, exploit evidence, or reproducible analysis.

Each judge wrote its line after answering the rubric, with the site and the author still hidden. Every answer behind this is in the table under Score.
