Common Convex Vulnerabilities We Detect

AI Agents Built for Convex

Our agents are trained on Convex architecture and equipped with specialized tooling for query functions, mutations, and real-time subscription security testing. They understand the nuances of Convex security that most pentesters miss.

Unprotected Query Functions

high

Query functions without proper authentication checks expose sensitive data to any client. Attackers can access private data by calling public query endpoints.

// Vulnerable: No auth check export const getUser = query({ args: { userId: v.id("users") }, handler: async (ctx, args) => { // Anyone can query any user! return await ctx.db.get(args.userId) }, })
// Fixed: Verify authentication export const getUser = query({ args: { userId: v.id("users") }, handler: async (ctx, args) => { const identity = await ctx.auth.getUserIdentity() if (!identity) throw new Error("Unauthorized") // Verify user can access this data return await ctx.db.get(args.userId) }, })

Insecure Mutation Functions

high

Mutation functions without authorization checks allow attackers to modify or delete data they should not have access to, leading to data corruption or privilege escalation.

// Vulnerable: No ownership check export const deletePost = mutation({ args: { postId: v.id("posts") }, handler: async (ctx, args) => { // Anyone can delete any post! await ctx.db.delete(args.postId) }, })
// Fixed: Verify ownership export const deletePost = mutation({ args: { postId: v.id("posts") }, handler: async (ctx, args) => { const identity = await ctx.auth.getUserIdentity() if (!identity) throw new Error("Unauthorized") const post = await ctx.db.get(args.postId) if (post?.authorId !== identity.subject) { throw new Error("Not authorized") } await ctx.db.delete(args.postId) }, })

HTTP Action Vulnerabilities

high

HTTP actions without proper input validation or authentication can be exploited for injection attacks, unauthorized data access, or service abuse.

// Vulnerable: No validation export const webhook = httpAction(async (ctx, req) => { const body = await req.json() // Trust external input directly! await ctx.runMutation(api.data.update, body) return new Response("OK") })
// Fixed: Validate and verify import { z } from "zod" const schema = z.object({ id: z.string(), data: z.object({ ... }) }) export const webhook = httpAction(async (ctx, req) => { const signature = req.headers.get("x-signature") if (!verifySignature(signature)) { return new Response("Invalid", { status: 401 }) } const body = schema.parse(await req.json()) await ctx.runMutation(api.data.update, body) })

Subscription Data Leakage

medium

Real-time subscriptions without proper filtering can leak sensitive data to unauthorized users. Attackers can subscribe to data streams they should not have access to.

// Vulnerable: Leaks all messages export const getMessages = query({ args: { channelId: v.id("channels") }, handler: async (ctx, args) => { // Returns all messages, even private ones return await ctx.db .query("messages") .filter((q) => q.eq(q.field("channelId"), args.channelId)) .collect() }, })
// Fixed: Filter by user access export const getMessages = query({ args: { channelId: v.id("channels") }, handler: async (ctx, args) => { const identity = await ctx.auth.getUserIdentity() if (!identity) return [] const membership = await ctx.db .query("memberships") .filter((q) => q.and( q.eq(q.field("channelId"), args.channelId), q.eq(q.field("userId"), identity.subject) )).first() if (!membership) return [] return await ctx.db.query("messages")... }, })
