feat(dos-id): sync organisation avatars from DOS ID - #17
Conversation
syncOrganisationForUser received the org avatar_url claim but dropped it on the floor, so organisations with an upstream avatar (e.g. the JOY org on prod) rendered as initials in Sign. Add syncOrganisationAvatarFromUrl (mirrors the user variant: SSRF-guarded fetch, create-swap-delete, fails soft) and wire it into the JIT org sync (existing and newly provisioned orgs) plus the org.updated webhook; org.created already routes through syncOrganisationForUser. Same source-of-truth policy as the user avatar: when DOS ID provides a URL it replaces the stored avatar on every sync.

🟡 IMPORTANT: Orphaned avatarImage record on failed organisation update
Failure Trace:
- A webhook or sync call invokes
syncOrganisationAvatarFromUrlwith a validavatarUrlbut anorganisationIdthat does not exist in the database (e.g., due to race condition with deletion or stale ID).
2.fetchOptimisedAvatarBase64succeeds and returns base64 bytes.
3.prisma.avatarImage.createexecutes successfully, inserting a new row into theavatarImagetable.
4.prisma.organisation.findUniquereturnsnullbecause the organisation does not exist.
5.prisma.organisation.updatethrows aPrismaClientKnownRequestError(P2025: Record not found).
6. The exception is caught by the outertry/catch, which logs the error and returnsnull.
7. The newly createdavatarImagerecord is never deleted, resulting in a permanent orphaned record in the database.

Bind SSRF validation to the connection used by fetch.
assertNotPrivateUrl performs a separate DNS lookup, but fetch(avatarUrl) performs its own resolution without a validated address or connection-time dispatcher. A DNS change between these operations can route the request to a private address. Use connection-time address pinning or rejection, and validate each permitted redirect before following it. Do not rely on an implicit global dispatcher unless this process explicitly installs and controls it.

Validate redirect destinations before fetching them.
If an attacker-influenced avatar URL redirects to a private address, fetch follows that redirect by default. assertNotPrivateUrl checks only the original URL. The server can therefore send a GET to an internal service. Disable automatic redirects, or validate each redirect destination before following it. (fetch.spec.whatwg.org)
Based on learnings, redirect targets need the same SSRF validation as the initial URL.

Denial of Service
Reachability: External
Exploitability: Moderate
CWE: CWE-400 — Uncontrolled Resource Consumption
Limit avatar bytes before buffering the response.
If an attacker-controlled endpoint sends a large body within five seconds, arrayBuffer() reads the full body before the code creates another base64 representation and runs image optimisation. Repeated syncs can exhaust server memory. Enforce a byte limit while reading the stream, and abort when the limit is exceeded. The timeout does not limit response size. (fetch.spec.whatwg.org)
Based on learnings, remote-resource fetches need a streaming response-size limit.

…ure alias Address review findings: the JIT org avatar sync is now fire-and-forget so the OAuth redirect latency stays independent of the org count (the sync logs its own failures), and the org.created webhook accepts the picture alias alongside avatar_url like the org.updated and user paths.

🛡️ Dismissed Claims
- Concurrency race condition deleting active avatar: The claim that concurrent calls could delete the currently active avatar is unsubstantiated. In the described race, both calls read the same
oldAvatarId(e.g.,A), create new images (B,C), and update the org. The last update wins (org points toC). Both then attempt to deleteA. DeletingAis correct behavior (it is no longer referenced). The scenario where one call reads the other's new ID as theoldAvatarIdwould require thefindUniqueto occur after the other call'supdate, but even then, deleting the other call's new image would only happen if that image was not the final winner. If it was the final winner, the org points to it, and deleting it would be a bug, but the code readsoldAvatarIdbefore creating the new image, so it cannot read a concurrently created new ID as the "old" ID. ThefindUniquehappens beforecreate, sooldAvatarIdis always the ID that existed before this call's new image was created. Thus, the race only results in redundant deletion attempts of the same old ID, which is safely handled by.catch(() => null). No concrete failure trace for deletion of the active avatar exists.

Why
Organisations with an upstream avatar render as initials in Sign:
syncOrganisationForUserreceived the DOS IDavatar_urlclaim but never used it (verified on prod: the JOY org has an avatar inpublic.organizationsbutsign.Organisation.avatarImageIdis null, so the org switcher shows "J").What
syncOrganisationAvatarFromUrl(organisationId, avatarUrl)mirroring the user variant: SSRF-guarded fetch, optimise, create-swap-delete of the AvatarImage row, fails soft (logs, returns null) so logins/webhooks never break on avatar errors.fetchOptimisedAvatarBase64used by both user and org variants.org.updatedwebhook.org.createdis covered automatically since it routes throughsyncOrganisationForUser.Verification
