### Impact The processPieceFromSource method (figure 4.1) is part of a task processing mechanism. The method writes pieces of data to storage, updating a Task structure along the way. The method does not update the structure’s usedTraffic field, because an uninitialized variable n is used as a guard to the AddTraffic method call, instead of the result.Size variable. ```golang var n int64 result.Size, err = pt.GetStorage().WritePiece([skipped]) result.FinishTime = time.Now().UnixNano() if n > 0 { pt.AddTraffic(uint64(n)) } ``` A task is processed by a peer. The usedTraffic metadata is not updated during the processing. Rate limiting is incorrectly applied, leading to a denial-of-service condition for the peer. ### Patches - Dragonfy v2.1.0 and above. ### Workarounds There are no effective workarounds, beyond upgrading. ### References A third party security audit was performed by Trail of Bits, you can see the [full report](https://github.com/dragonflyoss/dragonfly/blob/ma...
### Impact The Manager disables TLS certificate verification in two HTTP clients (figures 3.1 and 3.2). The clients are not configurable, so users have no way to re-enable the verification. ```golang func getAuthToken(ctx context.Context, header http.Header) (string, error) { [skipped] client := &http.Client{ Timeout: defaultHTTPRequesttimeout, Transport: &http.Transport{ TLSClientConfig: &tls.Config{InsecureSkipVerify: true}, }, } [skipped] } ``` A Manager processes dozens of preheat jobs. An adversary performs a network-level Man-in-the-Middle attack, providing invalid data to the Manager. The Manager preheats with the wrong data, which later causes a denial of service and file integrity problems. ### Patches - Dragonfy v2.1.0 and above. ### Workarounds There are no effective workarounds, beyond upgrading. ### References A third party security audit was performed by Trail of Bits, you can see the [full report]...
### Impact There are multiple server-side request forgery (SSRF) vulnerabilities in the DragonFly2 system. The vulnerabilities enable users to force DragonFly2’s components to make requests to internal services, which otherwise are not accessible to the users. One SSRF attack vector is exposed by the Manager’s API. The API allows users to create jobs. When creating a Preheat type of a job, users provide a URL that the Manager connects to (see figures 2.1–2.3). The URL is weakly validated, and so users can trick the Manager into sending HTTP requests to services that are in the Manager’s local network. ```golang func (p *preheat) CreatePreheat(ctx context.Context, schedulers []models.Scheduler, json types.PreheatArgs) (*internaljob.GroupJobState, error) { [skipped] url := json.URL [skipped] // Generate download files var files []internaljob.PreheatRequest switch PreheatType(json.Type) { case PreheatImageType: // Parse image manifest url s...
### Impact The /api/v1/jobs and /preheats endpoints in Manager web UI are accessible without authentication. Any user with network access to the Manager can create, delete, and modify jobs, and create preheat jobs. An unauthenticated adversary with network access to a Manager web UI uses /api/v1/jobs endpoint to create hundreds of useless jobs. The Manager is in a denial-of-service state, and stops accepting requests from valid administrators. ### Patches - Dragonfy v2.1.0 and above. ### Workarounds There are no effective workarounds, beyond upgrading. ### References A third party security audit was performed by Trail of Bits, you can see the [full report](https://github.com/dragonflyoss/dragonfly/blob/main/docs/security/dragonfly-comprehensive-report-2023.pdf).

The threat actor known as TA558 has been attributed to a fresh set of attacks delivering various remote access trojans (RATs) like Venom RAT to breach hotels in Brazil and Spanish-speaking markets. Russian cybersecurity vendor Kaspersky is tracking the activity, observed in summer 2025, to a cluster it tracks as RevengeHotels. "The threat actors continue to employ phishing emails with invoice
A China-aligned threat actor known as TA415 has been attributed to spear-phishing campaigns targeting the U.S. government, think tanks, and academic organizations utilizing U.S.-China economic-themed lures. "In this activity, the group masqueraded as the current Chair of the Select Committee on Strategic Competition between the United States and the Chinese Communist Party (CCP), as well as the

Cybersecurity researchers have warned of a new campaign that's leveraging a variant of the FileFix social engineering tactic to deliver the StealC information stealer malware. "The observed campaign uses a highly convincing, multilingual phishing site (e.g., fake Facebook Security page), with anti-analysis techniques and advanced obfuscation to evade detection," Acronis security researcher Eliad
