Descripción técnica

When parsing an uploaded Helm chart, Gitea decompressed the archive and read every tar entry while looking for `Chart.yaml` without limiting the decompressed size, and did so before the package size quota was checked; the quota only considers the compressed upload size. A user with package write access to an owner, for example their own account on an instance with open registration, could repeatedly upload small, highly compressed archives that make the server spend CPU time proportional to the decompressed size, degrading the availability of the Gitea instance. The issue does not allow code execution or data access.

——0A vulnerability was detected in Delgan loguru 0.7.3. The affected element is the function AnsiParser.feed of the file loguru/_colorizer.py of the component ANSI Color-Markup Parser. Performing a manipulation results in inefficient regular expression complexity. The attack is possible to be carried out remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.15h CVE-2026-633417.5 ALT

——9Aedes is an MQTT broker that can run on any stream server. Prior to 1.1.1, the MQTT broker does not bound topic depth or structural complexity before passing topics through `mqemitter` into `qlobber`. A `PUBLISH`, `SUBSCRIBE`, or registered `Will` message containing an excessively deep topic can reach `qlobber._split_words` in `lib/qlobber.js` and trigger an uncaught `too many words` exception. Calls from `handlers/subscribe.js` and the publishing logic are not protected against that exception, so it escapes to the `Node.js event loop` and terminates the entire broker. The `Will` path is independently reachable when a client disconnects ungracefully: it calls `broker.publish` directly and bypasses the `PUBLISH` handler. An attacker must be able to establish an `MQTT session`, authenticated or unauthenticated according to broker configuration. A successful attack disconnects all legitimate clients and prevents reconnection until the broker process restarts. This issue is fixed in version 1.1.1.2d CVE-2026-623006.5 MED

——5Filecoin Pin is an IPFS Pinning Service API implementation that pins to Filecoin's PDP service. In daemon deployments up to and including version 1.1.0, `POST /pins` in `src/filecoin-pinning-server.ts` checks a caller-supplied CID with `CID.parse` and passes it to `pinStore.pin`, but does not enforce request rate limits or per-user quotas. In `src/filecoin-pin-store.ts`, each pin independently schedules `_processPinInBackground` with `setTimeout` without a queue, semaphore or concurrency cap, then recursively traverses the full DAG using `helia.pins.add(cid)`. The per-pin Helia/Bitswap node in `src/create-pinning-helia.ts` has no application-level byte, block or traversal-time limits. Blocks are written under `carStoragePath` by `src/core/car/car-blockstore-base.ts` and `src/core/car/car-file-backend.ts`, with `stats.totalSize` updated only after writing. An authenticated caller, or an anonymous caller when `ALLOW_NO_AUTH=true`, can submit large DAGs and exhaust disk, network, CPU, memory and libp2p resources, causing service degradation or host/process failure and leaving partial CAR files requiring recovery. The default localhost binding and token requirement reduce exposure. Because nodes have no bootstrap or mDNS configuration, a CID alone may not be fetchable, but caller-supplied `origins` can point to a reachable attacker-controlled libp2p source; concurrent requests accelerate resource pressure. Version 1.1.1 documents operational mitigations but does not implement the missing resource controls.2d CVE-2026-622545.5 MED

——2LibreDWG is a free C library to read and write DWG files. Prior to 0.14, a specially crafted R13-R2000 DWG can trigger algorithmic resource exhaustion in `decode_R13_R2000` in `src/decode.c`. The class-decoding loop performs `realloc` on every iteration without a sanity check on `num_classes`. Manipulating that field forces an extremely slow allocation loop and denial of service when the file is parsed. Running the parser in a sandbox with memory limits is a workaround rather than a remediation. This issue is fixed in version 0.14.2d
