{"id":"AZL-105251","summary":"CVE-2026-102277 affecting package python-tensorboard 2.16.2-6","details":"The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to 1.1.21, 2.1.7, 3.0.9, and 5.0.12, the expand function handles untrusted {a},b}-shaped patterns with many trailing closing braces by restarting its scan once for each trailing closing brace. The successive full-input rescans with linear working-string growth cause quadratic CPU time and memory pressure that can block the Node.js event loop. The process eventually recovers, making the impact a recoverable CPU denial of service. This issue is fixed in versions 1.1.21, 2.1.7, 3.0.9, and 5.0.12.","modified":"2026-10-03T05:35:10Z","published":"2026-09-28T21:17:16Z","upstream":["CVE-2026-102277"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102277"}],"affected":[{"package":{"name":"python-tensorboard","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/python-tensorboard"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.16.2-6"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-105251.json"}}],"schema_version":"1.9.0"}
