LOW

Why flagged Downloads a prebuilt AppImage from cdn.dida365.cn, which is the official CDN for the Dida365/TickTick application (dida365.com is the Chinese version of TickTick); the checksum is pinned with a specific sha256sum, making silent substitution detectable. The main concern is that it's a prebuilt binary from a CDN rather than built from source, but this is standard practice for AppImage packaging and the host is plausibly the project's own official infrastructure.

Triggered rules

LOW AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (anthropic/claude-4.6-sonnet-20260217) reviewed the full PKGBUILD and judged it LOW (confidence 80%): Downloads a prebuilt AppImage from cdn.dida365.cn, which is the official CDN for the Dida365/TickTick application (dida365.com is the Chinese version of TickTick); the checksum is pinned with a specific sha256sum, making silent substitution detectable. The main concern is that it's a prebuilt binary from a CDN rather than built from source, but this is standard practice for AppImage packaging and the host is plausibly the project's own official infrastructure.

MEDIUM source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
