Previously minted tokens minted on the Chia blockchain using the CAT1 standard can be inflated to an arbitrary extent by any holder of any amount of the token. The total amount of the token can be increased as high as the malicious actor pleases. This is true for every CAT1 on the Chia blockchain regardless of issuance rules. This attack is auditable on chain, so maliciously altered coins can potentially be marked by off-chain observers as malicious.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":[],"references":["https://chia.net","https://www.chia.net/2022/07/25/upgrading-the-cat-standard.en.html","https://chia.net","https://www.chia.net/2022/07/25/upgrading-the-cat-standard.en.html"],"products":["chia:network_cat1_standard"],"source":"nvd","synced_at":"2026-10-19T21:34:18.502168378+00:00"},"epss":{"cve":"CVE-2022-36447","score":0.00859,"percentile":0.58492,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-pvjg-jwp3-mrj5","url":"https://osv.dev/vulnerability/GHSA-pvjg-jwp3-mrj5","summary":"chia-blockchain tokens can be inflated to an arbitrary extent","modified":"2024-12-02T05:40:04.740848Z","packages":[{"ecosystem":"PyPI","name":"chia-blockchain","purl":"pkg:pypi/chia-blockchain","ranges":["<=2.4.4rc3"],"fixed":[]}]},{"id":"PYSEC-2022-43072","url":"https://osv.dev/vulnerability/PYSEC-2022-43072","summary":"","modified":"2024-11-25T22:42:02.057936Z","packages":[{"ecosystem":"PyPI","name":"chia-blockchain","purl":"pkg:pypi/chia-blockchain","ranges":["<=2.4.4rc3"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
