CVE-2026-73247

HIGH8.6

Published 2026-08-11 · Source security-advisories@github.com

Description

Kestra is an open-source, event-driven orchestration platform. Prior to 2.0.0, Kestra's core/src/main/java/io/kestra/core/runners/pebble/functions/HttpFunction.java passes the user-controlled http() uri argument to URI.create() and the server-side HTTP client without restricting private, loopback, or link-local destinations, allowing an unauthenticated attacker to import and execute a flow that accesses internal services or cloud metadata.

CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N

CWE-918

CVE-2026-73249
calibre is an e-book manager. Prior to 9.12.0, the calibre Content Server endpoint POST /book-update-annotations/{library_id}/{book_id}/{fmt} in src/calibre/srv/books.py omits needs_db_write=True, causing Router.dispatch() to skip ctx.check_for_write_access() before update_annotations() passes attacker-controlled JSON to db.merge_annotations_for_book(), which allows a readonly user or an anonymous user on an unauthenticated deployment to persist unauthorized book annotation changes. This issue is fixed in version 9.12.0.

CVE-2026-73246
Kestra is an open-source, event-driven orchestration platform. Prior to 2.0.0-rc6, Kestra's worker/src/main/java/io/kestra/worker/endpoint/WorkerEndpoint.java serves GET /worker without authentication and serializes the complete live Task object, which can expose commands, environment variables, HTTP headers, connection details, plaintext credentials, and execution identifiers while the main API on port 8080 remains protected. This issue is fixed in 2.0.0-rc6.

CVE-2026-67558
The Mira Android companion app v4.5.15.4 identifies the paired Mira hormone analyzer by performing a substring match against the BLE advertisement name only, with no cryptographic peripheral authentication, MAC allowlist, or bonded-identity check. An attacker could capture live session token information and inject forged hormone measurements into the victim's cloud record and clinical trend view.

CVE-2026-66875
In the Mira hormone monitor device firmware v1.7.1.47 build 01070147, a remote unauthenticated attacker within BLE range (approximately 10–30 meters) can silently rebind the device to an attacker-controlled account, extract stored hormone measurements in cleartext, cause a denial-of-service via malformed or undocumented command opcodes, and passively track the user via a static random BLE address that never rotates.

CVE-2026-29036
cJSON versions 1.5.0 through 1.7.19 contain an incorrectly-resolved name or reference vulnerability in the decode_pointer_inplace() function within cJSON_Utils.c that allows unauthenticated attackers to cause JSON Patch operations to target wrong object keys by supplying crafted JSON Pointer escape sequences (~0 or ~1) in patch paths. Attackers can submit malicious RFC 6902 JSON Patch input to applications using cJSONUtils_ApplyPatches() or cJSONUtils_ApplyPatchesCaseSensitive() to silently corrupt data or delete unintended keys, potentially bypassing authorization controls in applications that rely on JSON Patch for access-controlled data modification.
