There are no guards on width/height or total pixels. A 10,000×10,000 PNG (~284 KB on disk) expands to ~100M pixels in memory during decode and triggers heavy CPU work in resize. - The first preview per attachment and size performs the heavy work; later requests are served from cache [keyvalue.Remember](../../tree/main/pkg/models/task_attachment.go#L220-L244).</p> <p>## Run The P…</p> <p><strong>Affected:</strong> Go: code.vikunja.io/api</p> <p>## Summary - Vulnerability: Unbounded image decoding and resizing during preview generation lets an attacker exhaust CPU and memory with highly compressed but extremely large-dimension images. - Affected code: - Decoding without bounds: [task_attachment.go:GetPreview](../../tree/main/pkg/models/task_attachment.go#L219-L229) - Resizing path: [resizeImage](../../tree/main/pkg/models/task_attachment.go#L293-L304) - Endpoint invoking preview: [GetTaskAttachment](../../tree/main/pkg/routes/api/v1/task_attachment.go#L195-L203) - Impact: First preview generation per attachment can allocate large memory and spend significant CPU; multiple attachments or concurrent requests can degrade or crash the service. - CVSS v3.1: 7.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)</p> <p>## Preconditions - API running locally (`http://localhost:8080`). - Task attachments enabled: `task_attachments_enabled=true` in [Info](../../tree/main/pkg/routes/api/v1/info.go#L82-L160). - Any authenticated user with write access to a task.</p> <p>## How It Works - Preview generation decodes the full image via `image.Decode` and resizes to a target width.
