@fullcalendar/core — Greenflagged

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures No source commit

Without SLSA provenance there is no cryptographic link between this tarball and the public source, so a manually published version cannot be tied back to a reviewed commit.

Accepted risks

Findings the reviewer chose to accept rather than block on.

Source	Rule	Reason	Accepted by	When
source-diff	obfuscated-file:internal-common.cjs	AI (source-diff): Bundled dist output, readable code, no malicious behavior; stable for this build.	ai	2026/07/22
source-diff	obfuscated-file:index.cjs	AI (source-diff): Bundled dual-module CJS output; readable re-exports/CSS, not obfuscation.	ai	2026/07/22
source-diff	obfuscated-file-transition:internal-common.js	AI (source-diff): Minified build artifact of established package; no payload.	ai	2026/07/22
source-diff	obfuscated-file-transition:internal.js	AI (source-diff): Bundler-generated re-export map; benign build output.	ai	2026/07/22
typosquat	typosquat.levenshtein:cors	AI (typosquat): @fullcalendar/core is the canonical FullCalendar core package, not a typosquat of cors; name similarity is coincidental.	ai	2026/04/28

HIGH New obfuscated file: internal-common.cjs source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

HIGH Modified file became obfuscated: internal-common.js source-diff

This file was readable in the previously greenflagged version and is now minified or obfuscated (lines over 3000 chars). A file that gains obfuscation between releases is a strong payload-swap indicator.

This file was readable in the previously greenflagged version and is now minified or obfuscated (lines over 3000 chars). A file that gains obfuscation between releases is a strong payload-swap indicator.
