Linux and Mac releases of the B2 command-line tool version 3.2.0 and below contain a key disclosure vulnerability that, in certain conditions, can be exploited by local attackers through a time-of-check-time-of-use (TOCTOU) race condition. The command line tool saves API keys (and bucket name-to-id mapping) in a local database file (`$XDG_CONFIG_HOME/b2/account_info`, `~/.b2_account_info` or a user-defined path) when `b2 authorize-account` is first run. This happens regardless of whether a valid key is provided or not. When first created, the file is world readable and is (typically a few milliseconds) later altered to be private to the user. If the directory is readable by a local attacker and the user did not yet run `b2 authorize-account` then during the brief period between file creation and permission modification, a local attacker can race to open the file and maintain a handle to it. This allows the local attacker to read the contents after the file after the sensitive information has been saved to it. Users that have not yet run `b2 authorize-account` should upgrade to B2 Command-Line Tool v3.2.1 before running it. Users that have run `b2 authorize-account` are safe if at the time of the file creation no other local users had read access to the local configuration file. Users that have run `b2 authorize-account` where the designated path could be opened by another local user should upgrade to B2 Command-Line Tool v3.2.1 and remove the database and regenerate all application keys. Note that `b2 clear-account` does not remove the database file and it should not be used to ensure that all open handles to the file are invalidated. If B2 Command-Line Tool cannot be upgraded to v3.2.1 due to a dependency conflict, a binary release can be used instead. Alternatively a new version could be installed within a virtualenv, or the permissions can be changed to prevent local users from opening the database file.", "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2022-23653", "reference_id": "", "reference_type": "", "scores": [ { "value": "0.00038", "scoring_system": "epss", "scoring_elements": "0.11903", "published_at": "2026-06-05T12:55:00Z" }, { "value": "0.00038", "scoring_system": "epss", "scoring_elements": "0.11819", "published_at": "2026-06-04T12:55:00Z" } ], "url": "https://api.first.org/data/v1/epss?cve=CVE-2022-23653" }, { "reference_url": "https://github.com/Backblaze/B2_Command_Line_Tool", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.7", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N" }, { "value": "5.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/Backblaze/B2_Command_Line_Tool" }, { "reference_url": "https://github.com/Backblaze/B2_Command_Line_Tool/commit/c74029f9f75065e8f7e3c3ec8e0a23fb8204feeb", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.7", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N" }, { "value": "5.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2025-04-23T14:10:03Z/" } ], "url": "https://github.com/Backblaze/B2_Command_Line_Tool/commit/c74029f9f75065e8f7e3c3ec8e0a23fb8204feeb" }, { "reference_url": "https://github.com/Backblaze/B2_Command_Line_Tool/security/advisories/GHSA-8wr4-2wm6-w3pr", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.7", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N" }, { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" }, { "value": "5.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2025-04-23T14:10:03Z/" } ], "url": "https://github.com/Backblaze/B2_Command_Line_Tool/security/advisories/GHSA-8wr4-2wm6-w3pr" }, { "reference_url": "https://github.com/pypa/advisory-database/tree/main/vulns/b2/PYSEC-2022-32.yaml", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.7", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N" }, { "value": "5.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/pypa/advisory-database/tree/main/vulns/b2/PYSEC-2022-32.yaml" }, { "reference_url": "https://nvd.nist.gov/vuln/detail/CVE-2022-23653", "reference_id": "CVE-2022-23653", "reference_type": "", "scores": [ { "value": "4.7", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N" }, { "value": "5.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://nvd.nist.gov/vuln/detail/CVE-2022-23653" }, { "reference_url": "https://github.com/advisories/GHSA-8wr4-2wm6-w3pr", "reference_id": "GHSA-8wr4-2wm6-w3pr", "reference_type": "", "scores": [ { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" } ], "url": "https://github.com/advisories/GHSA-8wr4-2wm6-w3pr" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/26740?format=api", "purl": "pkg:pypi/b2@3.2.1", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/b2@3.2.1" } ], "aliases": [ "CVE-2022-23653", "GHSA-8wr4-2wm6-w3pr", "PYSEC-2022-32" ], "risk_score": 3.1, "exploitability": "0.5", "weighted_severity": "6.2", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-qyby-143d-b7gz" } ], "fixing_vulnerabilities": [], "risk_score": "3.1", "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/b2@0.4.0" }
