CVE-2026-33817

Analysis

CVE-2026-33817 was assigned to a potential vulnerability in the bbolt key-value database, a fork of Bolt used in high-load production environments [1]. The vulnerability description and related fix in pull request #1171 appeared to address a possible issue in the Bucket.Stats() function where a missing guard for p.Count() == 0 on branch pages could lead to an out-of-bounds access [2]. The fix added a zero-count check before calculating the last branch page element and computing used bytes [2].

However, the CVE has been rejected because the issue was determined to be a false positive [4]. The National Vulnerability Database (NVD) lists the rejection reason, and the Go vulnerability database also reflects that no actual vulnerability was present [3]. No further action is required for users, as the fix in PR #1171 is an improvement for code robustness rather than a security patch [2]. Systems running bbolt remain unaffected by any material security flaw from this identifier.

Impact and

Mitigation

Since CVE-2026-33817 is false positive, there is no actual impact, and no mitigation or patching is needed beyond normal maintenance.
