Relapse Exploit Docker

Container packaging for PS5 Relapse Exploit. The upstream project is pinned as a Git submodule, and the image build verifies the SHA-256 digest of every executable payload before including it.

The Compose stack also includes a local PS5 User Guide gateway: authoritative DNS for manuals.playstation.net, HTTP/HTTPS redirect to the local exploit, allowlisted DNS forwarding for the homebrew store, and NXDOMAIN for every other domain so the console cannot resolve PSN or update services.

Use this only on consoles you own or are authorized to test. The exploit can panic the console, corrupt kernel state, expose administrative services, and execute arbitrary code with elevated privileges.

Documentation:

• PS5 setup, DNS, deployment, and troubleshooting
• Maintainer and agent handoff
• Y2JB / Relapse controlled test record
• External payload candidate evidence
• Repository instructions for coding agents

Current deployment

The maintained LAN deployment runs on net-utils01 from /opt/relapse-exploit-docker:

Service	LAN endpoint	Purpose
Relapse page	http://192.168.20.30:8000/	Exploit page and payload assets
Restricted DNS	192.168.20.30:53 UDP/TCP	User Guide override and store allowlist
User Guide gateway	192.168.20.30:80 and :443 TCP	Redirect to the local Relapse page

Configure the PS5 with primary DNS 192.168.20.30 and secondary DNS 0.0.0.0. The DNS gateway resolves manuals.playstation.net locally and forwards only homebrew.page, itsplk.github.io, store.spectrumlibrary.online, api.github.com, github.com, raw.githubusercontent.com, release-assets.githubusercontent.com, prosperopatches.com, cdn.prosperopatches.com, image.api.playstation.com, and gmedia.playstation.com to its configured upstream resolver. These names cover the homebrew store, PS5 Payload Manager, Spectrum Library, and BlackBox's catalog, updates, and artwork; every other name receives NXDOMAIN.

The console needs LAN access to DNS UDP/TCP 53 and TCP 80, 443, and 8000 on 192.168.20.30. For the online applications it also needs WAN egress on TCP 443 to the allowlisted domains; no WAN ingress rule is required. The server needs DNS egress on UDP/TCP 53 to its configured resolver (1.1.1.1 by default).

The Payload Manager supports arbitrary custom repository URLs. Those hosts are not allowed automatically: review the repository JSON, payload URLs, checksums, and redirect destinations before adding another exact hostname to FORWARDED_DOMAINS.

Spectrum Library is distributed without source code in its repository. Static review of its 1.4.8 ELF identified store.spectrumlibrary.online for its API and api.github.com for update checks. Catalog responses can supply additional cover, manifest, and package URLs; these unknown hosts remain blocked until observed and reviewed. The Spectrum API returned HTTP 502 during the 2026-10-07 review, so DNS availability alone does not guarantee that its catalog will load.

BlackBox v1.0.5 uses raw.githubusercontent.com for its catalog and update JSON, the existing GitHub hosts for its own release files, and the Prosperopatches and PlayStation media hosts for artwork. Its catalog also advertises third-party game files from Archive.org and Vikingfile. Those download providers are deliberately not allowlisted: browsing, artwork, and application updates work without granting the console access to unreviewed game files that frequently lack SHA-256 hashes.

To deploy a reviewed commit:

ssh net-utils01
cd /opt/relapse-exploit-docker
git pull --ff-only
git submodule update --init --recursive
docker compose up -d --build
docker compose ps
curl -I http://127.0.0.1:8000/

Both Compose services must report healthy. Runtime changes require the rebuild above; documentation-only changes need only the fast-forward pull.

Clone and build

git clone --recurse-submodules <repository-url>
cd relapse-exploit-docker
docker compose build

For an existing clone:

git submodule update --init --recursive
docker compose build

Run

docker compose up -d

Open http://HOST-IP:8000/ from the PS5. View the service status with:

docker compose ps
docker compose logs -f

Stop it with docker compose down.

By default, port 8000 is exposed on every host interface so the PS5 can reach it. Restrict it to one host address when possible:

HOST_BIND=192.168.1.10 HOST_PORT=8000 docker compose up -d

Do not expose this service to the internet. Prefer an isolated local network.

Update upstream

Review upstream changes before updating because the served JavaScript and payloads ultimately execute with kernel privileges.

git -C app fetch origin
git -C app checkout <reviewed-commit>
sha256sum app/payloads/*

After reviewing the new binaries, update payloads.sha256, rebuild, test, and commit both the submodule pointer and checksum changes together.

The currently pinned upstream snapshot includes only the kernel exploit payload and the ELF loader. It no longer bundles etaHEN, KStuff, or ShadowMount+ because upstream removed those compatibility-sensitive payloads. After the loader starts, send any separately reviewed ELF to the PS5 on TCP port 9021 with an external payload sender.

Container hardening

The runtime image:

• contains only the files required by the exploit page;
• runs as numeric user/group 65532:65532;
• has a read-only filesystem, all Linux capabilities dropped, and no-new-privileges;
• disables directory listings and browser caching;
• adds restrictive browser security headers;
• does not expose the upstream .git directory.

These controls protect the host-side web server. They do not make the PS5 exploit or its precompiled payloads intrinsically safe.
