PrivateBin

产品介绍

PrivateBin 是零知识加密的临时文本分享服务。文本内容在浏览器中加密和解密，服务端只保存密文。

主要功能

浏览器端加密和解密的临时文本分享
文件系统持久化后端，保留服务器盐和限流状态
只读根文件系统与最小临时写入目录

访问说明

安装后通过 http://<服务器 IP>:<端口> 访问，实际端口以 PANEL_APP_PORT_HTTP 为准。生产环境应通过可信反向代理提供 HTTPS，并限制管理服务器的网络暴露范围。

数据持久化

APP_DATA_DIR 挂载到容器的 /srv/data，其中保存文本数据、服务器盐和限流状态。该路径必须位于应用版本目录内（默认 ./data）；安装与升级脚本会拒绝绝对路径及目录外路径，避免误改宿主机文件权限。脚本会将该目录设置为官方镜像要求的 UID 65534、GID 82。升级、迁移或卸载前请备份该目录；卸载不会删除绑定目录中的用户数据。

安全说明

容器以只读根文件系统运行，仅允许写入 /srv/data 以及 /tmp、/run、/var/lib/nginx/tmp 三个临时目录。
上游镜像内部通过 s6 协调 Nginx 与 PHP-FPM；它仍是单个 Compose 服务，但不适合纳入自动升级或自动合并策略。
2026-07-27 的 Trivy 扫描在固定镜像中发现 0 个 Critical 和 1 个 High：CVE-2026-42533（Nginx 对特制 HTTP 请求的代码执行风险）。仅向可信用户开放，保持反向代理与镜像更新；上游修复镜像经验证后应尽快升级。

Introduction

PrivateBin is a zero-knowledge encrypted paste service. Data is encrypted and decrypted in the browser, so the server stores ciphertext only.

Features

Browser-side encryption and decryption for shared pastes
Filesystem persistence for the server salt and rate-limit state
Read-only root filesystem with minimal temporary writable paths

Usage Notes

Access the service at http://<server-ip>:<port> after installation. Put a trusted TLS reverse proxy in front of it for production exposure.
APP_DATA_DIR persists the filesystem backend, server salt, and rate-limit state. It must remain relative to the application version directory (default ./data); absolute and outside paths are rejected to protect host file ownership. Back it up before upgrades or migrations.
The container uses a read-only root filesystem with the upstream-required writable data and temporary paths only.
The 2026-07-27 Trivy scan found 0 Critical and 1 High in the pinned image: CVE-2026-42533 (Nginx code-execution risk for crafted HTTP requests). Expose it only to trusted users, retain a reverse proxy, and update promptly when an upstream-fixed image is verified.
